Object Oriented
Thinking
Objectives
■ To apply class abstraction to develop software (§10.2).
■ To explore the differences between the procedural paradigm and object-
oriented paradigm (§10.3).
■ To discover the relationships between classes (§10.4).
■ To design programs using the object-oriented paradigm (§§10.5–10.6).
■ To create objects for primitive values using the wrapper classes (Byte,
Short, Integer, Long, Float, Double, Character, and Boolean)(§10.7).
■ To simplify programming using automatic conversion between primitive
types and wrapper class types (§10.8).
■ To use the BigInteger and BigDecimal classes for computing very large
numbers with arbitrary precisions (§10.9).
■ To use the String class to process immutable strings (§10.10).
■ To use the StringBuilder and StringBuffer classes to process mutable strings
(§10.11).
Class Abstraction
• Class abstraction is the separation of class implementation from the use of
a class. The details of implementation are encapsulated and hidden from
the user. This is known as class encapsulation. Java provides many levels of
abstraction, and class abstraction separates class implementation from
how the class is used. The creator of a class describes the functions of the
class and lets the user know how the class can be used. The collection of
methods and fields that are accessible from outside the class, together
with the description of how these members are expected to behave, serves
as the class’s contract. As shown in Figure 10.1, the user of the class does
not need to know how the class is implemented. The details of
implementation are encapsulated and hidden from the user. This is called
class encapsulation. For example, you can create a Circle object and find
the area of the circle without knowing how the area is computed. For this
reason, a class is also known as an abstract data type (ADT).
OBJECTS AND CLASSES
Constructors
A constructor with no parameters is referred to as a
no-arg constructor or default constructor.
· Constructors must have the same name as the
class itself.
· Constructors do not have a return type—not
even void.
· Constructors are invoked using the new operator
when an object is created. Constructors play the
role of initializing objects.
10
Constructors
Constructors are a special
Circle() {
} kind of methods that are
invoked to construct objects.
Circle(double newRadius) {
radius = newRadius;
}

11
Default Constructor
A class may be defined without constructors. In
this case, a no-arg constructor with an empty body
is implicitly defined in the class. This constructor,
called a default constructor, is provided
automatically only if no constructors are explicitly
defined in the class.

12
Creating Objects Using
Constructors
new ClassName();

Example:
new Circle();

new Circle(5.0);

13
Declaring Object Reference Variables
To reference an object, assign the object to a
reference variable.

To declare a reference variable, use the syntax:

ClassName objectRefVar;

Example:
Circle myCircle;

14
Declaring/Creating Objects
in a Single Step
ClassName objectRefVar = new ClassName();

Assign object reference Create an object

Example:
Circle myCircle = new Circle();

15
Accessing Object’s Members
❑ Referencing the object’s data:
objectRefVar.data
e.g., myCircle.radius

❑ Invoking the object’s method:

objectRefVar.methodName(arguments)
e.g., myCircle.getArea()

16
ARRAYS
A Main Method is Just a Regular Method

and easy to maintain (§6.6).
■ To use method overloading and understand ambiguous overloading (§6.8).

(§6.10).
■ To design and implement methods using stepwise refinement (§6.10).

Introduction to Java Programming, 10th Edition,Y.Daniel Liang

• A parameter is actually a local variable. The scope of a method
parameter covers the entire method. A variable declared in the initial-
action part of a for-loop header has its scope in the entire loop.
However, a variable declared inside a for-loop body has its scope
limited in the loop body from its declaration to the end of the block
that contains the variable, as shown in Figure

Introduction to Java Programming, 10th Edition,Y.Daniel Liang

Scope of Local Variables, cont.
You can declare a local variable with the
same name multiple times in different non-
nesting blocks in a method, but you cannot
declare a local variable twice in nested
blocks.

Identifiers

An identifier is a sequence of characters that consist of

letters, digits, underscores (_), and dollar signs ($).
An identifier must start with a letter, an underscore (_),
or a dollar sign ($). It cannot start with a digit.
An identifier cannot be a reserved word.
An identifier cannot be true, false, or
null.
An identifier can be of any length.

Introduction to Java Programming,
Variables
Variables are used to represent values that may be changed in the program.

Variables are for representing data of a certain type. To use a variable, you declare
it by telling the compiler its name as well as what type of data it can store. The
variable declaration tells the compiler to allocate appropriate memory space for the
variable based on its data type.
Introduction to Java Programming, 10th Edition,Y.Daniel Liang 16
Introduction to Java Programming, 10th Edition,Y.Daniel Liang 17
Named Constants

A constant must be declared and initialized in the same statement. The word
final is a Java keyword for declaring a constant.

Introduction to Java Programming, 10th Edition,Y.Daniel Liang 18

Introduction to Java Programming, 10th Edition,Y.Daniel Liang 19
Naming Conventions
Choose meaningful and descriptive names.
Variables and method names:
• Use lowercase. If the name consists of several words,
concatenate all in one, use lowercase for the first
word, and capitalize the first letter of each subsequent
word in the name. For example, the variables
radius and area, and the method
computeArea.

Class names:
• Capitalize the first letter of each word in

Numeric Types

Introduction to Java Programming, 10th Edition,Y.Daniel Liang 22

Introduction to Java Programming, 10th Edition,Y.Daniel Liang 23
• Java uses four types for integers: byte, short, int, and long.
Choose the type that is most appropriate for your variable.
For example, if you know an integer stored in a variable is
within a range of a byte, declare the variable as a byte.

• Java uses two types for floating-point numbers: float and

double. The double type is twice as big as float, so the
double is known as double precision and float as single
precision. Normally, you should use the double type,
because it is more accurate than the float type.

Conversion Rules
When performing a binary operation involving two
operands of different types, Java automatically
converts the operand based on the following rules:

1. If one of the operands is double, the other is

converted into double.
2. Otherwise, if one of the operands is float, the other is
converted into float.
3. Otherwise, if one of the operands is long, the other is
converted into long.
4. Otherwise, both operands are converted into int.

SampleClassName).
▪ A class name is an identifier—a series of characters consisting
of letters, digits, underscores (_) and dollar signs ($) that does
not begin with a digit and does not contain spaces.
▪ Java is case sensitive—uppercase and lowercase letters are
distinct—so a1 and A1 are different (but both valid)
identifiers.

is used in this program.
 Variable
▪ A location in the computer’s memory where a value can be stored for
use later in a program.
▪ Must be declared with a name and a type before they can be used.
▪ A variable’s name enables the program to access the value of the
variable in memory.
▪ The name can be any valid identifier.
▪ A variable’s type specifies what kind of information is stored at that
location in memory.

(C) 2010 Pearson Education, Inc. All

rights reserved.
 Scanner
▪ Enables a program to read data for use in a program.
▪ Data can come from many sources, such as the user at the keyboard or a
file on disk.
▪ Before using a Scanner, you must create it and specify the source of
the data.
 The equals sign (=) in a declaration indicates that the variable
should be initialized (i.e., prepared for use in the program) with
the result of the expression to the right of the equals sign.
 The new keyword creates an object.
 Standard input object, System.in, enables applications to read
bytes of information typed by the user.
 Scanner object translates these bytes into types that can be
used in a program.

 Scanner method nextInt
number1 = input.nextInt(); // read first number from
user
▪ Obtains an integer from the user at the keyboard.
▪ Program waits for the user to type the number and press the
Enter key to submit the number to the program.
 The result of the call to method nextInt is placed in
variable number1 by using the assignment operator, =.
▪ “number1 gets the value of input.nextInt().”
▪ Operator = is called a binary operator—it has two operands.
▪ Everything to the right of the assignment operator, =, is always
evaluated before the assignment is performed.

 Arithmetic
sum = number1 + number2; // add numbers
▪ Assignment statement that calculates the sum of the variables
number1 and number2 then assigns the result to variable sum
by using the assignment operator, =.
▪ “sum gets the value of number1 + number2.”
▪ In general, calculations are performed in assignment statements.
▪ Portions of statements that contain calculations are called
expressions.
▪ An expression is any portion of a statement that has a value
associated with it.

rights reserved.
 Variables
▪ Every variable has a name, a type, a size (in bytes) and a value.
▪ When a new value is placed into a variable, the new value
replaces the previous value (if any)
▪ The previous value is lost.

 Arithmetic operators are summarized in Fig. 2.11.
 The asterisk (*) indicates multiplication
 The percent sign (%) is the remainder operator
 The arithmetic operators are binary operators because
they each operate on two operands.
 Integer division yields an integer quotient.
▪ Any fractional part in integer division is simply discarded (i.e.,
truncated)—no rounding occurs.
 The remainder operator, %, yields the remainder after
division.

(C) 2010 Pearson Education, Inc. All

rights reserved.
(C) 2010 Pearson Education, Inc. All

 Arithmetic expressions in Java must be written in
straight-line form to facilitate entering programs into
the computer.
 Expressions such as “a divided by b” must be written
as a / b, so that all constants, variables and operators
appear in a straight line.
 Parentheses are used to group terms in expressions in
the same manner as in algebraic expressions.
 If an expression contains nested parentheses, the
expression in the innermost set of parentheses is
evaluated first.

(C) 2010 Pearson Education, Inc. All

rights reserved.
 Rules of operator precedence
▪ Multiplication, division and remainder operations are applied first.
▪ If an expression contains several such operations, they are applied from
left to right.
▪ Multiplication, division and remainder operators have the same level of
precedence.
▪ Addition and subtraction operations are applied next.
▪ If an expression contains several such operations, the operators are
applied from left to right.
▪ Addition and subtraction operators have the same level of precedence.
 When we say that operators are applied from left to right, we are
referring to their associativity.
 Some operators associate from right to left.
 Complete precedence chart is included in Appendix A.

 As in algebra, it’s acceptable to place redundant
parentheses (unnecessary parentheses) in an ex-
pression to make the expression clearer.

(C) 2010 Pearson Education, Inc. All

rights reserved.
(C) 2010 Pearson Education, Inc. All

 Condition
▪ An expression that can be true or false.
 if selection statement
▪ Allows a program to make a decision based on a condition’s value.
 Equality operators (== and !=)
 Relational operators (>, <, >= and <=)
 Both equality operators have the same level of precedence,
which is lower than that of the relational operators.
 The equality operators associate from left to right.
 The relational operators all have the same level of
precedence and also associate from left to right.

 An if statement always begins with keyword if,
followed by a condition in parentheses.
▪ Expects one statement in its body, but may contain multiple
statements if they are enclosed in a set of braces ({}).
▪ The indentation of the body statement is not required, but it
improves the program’s readability by emphasizing that
statements are part of the body.
 Note that there is no semicolon (;) at the end of the
first line of each if statement.
▪ Such a semicolon would result in a logic error at execution
time.
▪ Treated as the empty statement—semicolon by itself.
