Question

What "RETURN" statement and How to use "RETURN" statement in Java when public a method or class ?

Answer 1

There are two ways to use this return: 1)we can return the methodthat is method executes a block and returns (in any case, something will
return. The only question that you need or what that is)

example:
public static String getText (int index) {
return"Hello World". substring (index); }

public static void main(String[] args)
{
Stringtext=getText(0);//getText(0) returns "Hello World"
System.out.println( text);//prints result }

2) in the second case we can use return to "undo" ablock.example

void setText ()
{
if (foo) return;
this.text ="Hello World";
}
