Today, we were taught about Exception Handling. An exception is a run-time error. Exception Handling is managed by 5 keywords - try, throw, throws, catch and finally. All exception types are subclass of built-in class "Throwable". This concept has 2 advantages:-
*We can fix errors ourselves.
*It prevents programs from automatically terminating.

Example:-

public class ExceptionHandling {
    public static void main(String args[])
    {
        int a,d;
        try{
            d=11;
            a=d/0;
            System.out.println("This wont be printed.");
        }
        catch(ArithmeticException e)   
        {
            System.out.println("Division by Zero");
        }
            System.out.println("This is an after Catch statement");
    }
    
}




OUTPUT:




Division by Zero
This is an after Catch statement
