[FIXED] How to println value from function?

Issue

I would like to println value 5 from void add_up but I cant write name of function: add_up to System out.println(). How to println out of main and get out of void add_up? Thank´s.

import java.io.IOException;

public class function{

    public static void main(String[] args) throws IOException {

            System.out.println(add_up);

    }

    public int add_up(){
    int a = 5;
    return a;
    }
}

Solution

In order to call the method you need to add () after its name.

import java.io.IOException;

public class Function {

    public static void main(String[] args) {
      System.out.println(add_up());
    }

    public static int add_up(){
      int a = 5;
      return a;
    }
}

Secondly, you needed to make your method static so the static method main can access it.
