So if void doesnt return a value then whats the point if it? (As in what does void do?)

Answer 1

Not all methods need to give back a value once they do their task. They simply do their work when they're called, and don't produce a value. But all methods must have a return type, so void is used to return nothing.

Answer 2

class Demo1
{
public static void main(String[] args)
{
System.out.println("Hello world!");
}
}

this does not return anything. But print some message.

Answer 3

Void function and method do not return value but do some work like print some value.

Answer 4

@Joshua Lazaro
If you use same content more than once. It is better to make the content to function

Answer 5

To tell the caller: "Hey, I'm a method, I do some useful task, but I do not return anything!"
So the caller, knowing this, can not expect something to be returned.

Answer 6

Void in Java is a uninstantiable placeholder type. The compiler requires that all Method signatures contain a return type. Void is a placeholder type that is used to tell the compiler that nothing is being returned and that the return keyword is not required for this method.

Answer 7

Ahhh, okay Thanks!!!!

Answer 8

Yes, but that is not the same as returning a value or object from a method.

int x = getInt();

String stuff = printSomething("Stuff"); // this would produce an error as nothing is returned from the method to be stored in the stuff variable.

public static void printSomething(String something) {
System.out.println(something);
}

public static int getInt() {
return 42;
}

Answer 9

But cant you just use a simple system.out.println to print something out?
