Hi Ramesh

whenever we create a class whic is sub class to Exception, those classes treated as compile time exceptions.

public CheckedException extends Exception {
    public CheckedException() {}
    public CheckedException(String string) {
       super(string);
    }
}

whenever we create a class whic is sub class to RuntimeException, those classes treated as run time excetions.

public UncheckedException extends RuntimeException { public UncheckedException() {} public UncheckedException(String string) { super(string); } }
