Experiment : 6
Aim:Program to create class with members and methods, accept and display details for single object.define a
class to represent a bank account. Include the following members: name of the depositor, account number,
type of account balance amount in the account Methods:
1.to assign initial values
2.to deposit an amount
3.to withdraw an amount after checking balance.
4.to display the name & balance
OBJECTIVE : To make students understand the basics of class,methods and how to retrieve data in Java
Description :
What is class and object in java. How to create object
How to define the structure of java program
How to define method and how to access method of a class
