17.Explain user defined exception in java with a suitable example. In java we can create our own exception class and throw that exception using throw keyword. These exceptions are known as user-defined or custom exceptions.

class JavaException{
   public static void main(String args[]){
  try{
       throw new MyException(2);
       // throw is used to create a new exception and throw it.
  }
 catch(MyException e){
    System.out.println(e) ;
 }
}
}
class MyException extends Exception{
   int a;
   MyException(int b) {
     a=b;
   }
   public String toString(){
     return ("Exception Number =  "+a) ;
  }
