Practical No 7
Aim: Implement the concept of exception in Java
Theory:
The Exception Handling in Java is one of the powerful mechanisms to handle the runtime
errors so that the normal flow of the application can be maintained.
What is Exception in Java?
Dictionary Meaning: Exception is an abnormal condition.
In Java, an exception is an event that disrupts the normal flow of the program. It is an object
which is thrown at runtime.
What is Exception Handling?
Exception Handling is a mechanism to handle runtime errors such as
ClassNotFoundException, IOException, SQLException, ArithmeticException,
ArrayIndexOutOfBoundsException.
Advantage of Exception Handling
The core advantage of exception handling is to maintain the normal flow of the application.
An exception normally disrupts the normal flow of the application; that is why we need to
handle exceptions.
Program:
public class MultipleCatchBlock1 {
public static void main(String[] args) {
try{
int a[]=new int[5];
a[5]=30/0;
String s=null;
System.out.println(s.length());
}
catch(ArithmeticException e)
{
System.out.println("Arithmetic Exception occurs");
}
catch(ArrayIndexOutOfBoundsException e)
{
System.out.println("ArrayIndexOutOfBounds Exception occurs");
}
catch(Exception e)
{
System.out.println("Parent Exception occurs");
}
System.out.println("rest of the code");
}
}
Conclusion: Thus implement the concept of exception in Java.
