Java Programming Practical 13
Question 1
Write the simple program for throwing our own exceptions
OwnExceptionDemo.java
Java
import java.util.Scanner;
class MyException extends Exception
{
public MyException(String message)
{
super(message);
}
}
public class OwnExceptionDemo
{
public static void main(String[] args)
{
try {
{
throw new MyException("This exception is manually thrown");
}
}
catch (MyException e)
{
System.out.println(e.getMessage());
}
}
}
Output
Question 2
Define an exception called “NotMatchExceptons” that is thrown when a string is not equals to “India”. Write a program that uses this exceptions.
NotMatchDemo.java
Java
import java.util.Scanner;
class NotMatchExcepton extends Exception
{
public NotMatchExcepton(String message)
{
super(message);
}
}
public class NotMatchDemo
{
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);
try {
System.out.print("Enter your string: ");
String str = scanner.nextLine();
if (!str.equals("India"))
{
throw new NotMatchExcepton("String does not match");
}
System.out.println("String matched");
}
catch (NotMatchExcepton e)
{
System.out.println(e.getMessage());
}
}
}
Output
