String can't change. But int, char can change

Question

I\'ve read that in Java an object of type String can\'t change. But int and char variables can. Why is it? Can you give me an example?

Thank you. (I am a newer -_- )

Answer 1

int and char can't change either. As with strings, you can put a different value into the same variable, but an integer itself doesn't change. 3 will always be 3; you can't modify it to be 4.
