Adding bytes and getting int

[Prakash Rai]

 class A{
	public static void main(String arg[]){
	byte b=20;
	byte c=30;
	//byte d=b+c; It is giving error 
	int d=b+c;
	System.out.println(d);
	}
	}

Q1. If we are adding byte and byte then it should also result byte but it is int. Why?

Agree. We have a relatively new feature, which allows me to make the new posts into a new topic.

Voilà!

And I think you have given a sufficient answer.
