Hello friends, I have a few doubt

1. can you implement an abstract method like

abstract void meet()
{
System.out.println("Hello");
}?

2. In the scenario,
boolean b = false;
System.out.println("This is "+b);
Can we append boolean value to String with "+" operator?


3.If a method does not throw any Exception, can its overriding method throw Exception?

Hi Krishna, you can find the answer to your questions quickly by writing a small test program. Try it - you learn much more by experimenting yourself than when someone else just gives you the answer.

Please check this.
1. No you cannot abtract method means no method body this is fine
abstract void meet();

2. Yes anything String + is printable so this will print
This is false.

3.Overriding methid cannot throw any checked exception but yes it can throw unchecked exceptions.
