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.
