Here is another example :-
 
 
class Hello extends Exception{
Hello(){
System.out.println(“Hello from contructor”);
}
public String toString(){
return “HELLO EXCEPTION HAS OCCURRED”;
}
public String getMessage(){
return “not found something”;
}
}
class MyException{
public static void main(String as[]){
int x =10;
try{
if(x<20){
throw new Hello();
}
}
catch(Hello e){
System.out.println(e.getMessage());
}
}
}
