Java code to find operating system

Question

I am very new at coding in Java and I want to write a code to find out my operating system through a dialogue box (Windows). I wrote this code but I am not sure how to completely implement it.

Please let me know what I am doing wrong in simple terms as I am a beginner.

import java.awt.*;
import javax.swing.*;


public class JavaTut {
  public static void main(String[] args) {
    JOptionPane.showMessageDialog(null,System.getProperty("os.name").list(System.out));
    Toolkit.getDefaultToolkit().beep();
 }
}

don't use a screenshot copy the code into the post and format it. — twain249, May 21 '17 at 12:03

Instead of System.getProperty("os.name").list(System.out), use System.getProperty("os.name").

Example main method:

public static void main(String[] args) {
    JOptionPane.showMessageDialog(null, System.getProperty("os.name"));
}
