Java Customized Exceptions

Sometimes to fulfill the programming requirement we can define our own exceptions such type of exceptions are called customized exceptions.

Let's take an example of customized exceptions.

import java.util.*;
class TooYoungException extends RuntimeException
{ 
       TooYoungException (String s)
       {
           super(s);
        }
} 
class TooOldException extends RuntimeException
{ 
       TooOldException (String s)
       {
           super(s);
        }
} 
class CustomizeException
{
     public static void main(String [] args)
     { 
         Scanner sc = new Scanner(System.in);
         System.out.println("Enter the age ");
         int age=sc.nextInt();
         if(age>60)
         {
            throw new TooOldException("Your age is already crossed the marriage age...
                                         try In next birth... ");
         }
         else if(age<18)
         {
            throw new TooYoungException("Please wait some time...
                                         You will get your best match soon... ");
          }
          else
          {
             System.out.println("Congrats!!!You are eligible for marriage..
                                  you will get details of your match by email!!");
          }
      }
 }

Output is:-
