Not sure how to do this

Question about the task

As simple as 2+2

Java Syntax, Level 1, Lesson 8

Resolved

I don't get how to do this because I dont get how to call a method aka the sum like what do I do here?

package com.codegym.task.task01.task0128; /* As simple as 2+2 */ public class Solution { public static void main(String[] args) { int sum = (2 + 2); System.out.println(sum); } public static void sum(int a, int b) { int c = a + b; System.out.print(c); } }

public class Solution { public static void main(String[] args) { //write your code here sum(2,2); } public static void sum(int a, int b ) { int c = a + b; System.out.print(c);

I personally used google a lot going through the levels to help with understanding things. It may surprise you that you have already been using methods. The System.out.println() is a method that accepts a string parameter and outputs it to screen. The code is hidden from you, but is part of the System class that is available for us to use. It works the same exact way that any method works, you pass values to it inside of the parentheses (this is called the method parameters). You use the sum method the same exact way, by typing its name followed by parentheses, and then parameters. The parameters for the sum method are restricted to two integers in this case. So to solve this task, using the above code as example, remove lines 10 and 11, add one line that is the method call for sum with the 2 integers that you want to use as parameters (2 and 2 according to the task). Just like println you don't declare variables in method calls, this is incorrect:

sum(int 2, int 2);

Try it out and see if you can solve with this help.

The program should display the sum of 2 and 2.(int a =2,int b=2); The main method should call the sum method with the arguments 2 and 2.--sum(a,b); The main method should not call a screen output method(should not use System.out.println()).

Try this int a=2; int b=2; sum(a,b);

Remove println method from main and write sum(2,2) in main and it will be ok. It will call sum method and pass two arguments to it. Also, int sum = (2+2) is not required.
