The method println(boolean) in the type PrintStream is not applicable for the arguments (void)

Question

I am getting an error when I try executing the following code:

package Abc;

public class Class3 {

    public void another() {
        System.out.println("Hello World");
    }

    public static void main(String[] args) {
        Class3 obj1 = new Class3();
        System.out.println(obj1.another());
    }

}

The error is:

The method println(boolean) in the type PrintStream is not applicable for the arguments (void)

Answer 1

Your another() function return type is 'void' which essentially says it is defined to return nothing.

package Abc;

public class Class3 {
    public void another() {
       System.out.println("Hello World");
    }

   public static void main(String[] args) {
    Class3 obj1 = new Class3();
    obj1.another();
    }

}

Println() function expect something while your method doesn't return anything. That's why you are getting error.
