Improving my Java object-oriented? Review!

Did I improve since then?

I have been writing this program today, and tried my best to improve my object-oriented understanding.

Mains.java:

import games.GameHandler;
import java.util.Scanner;
import java.io.*;

    public class Mains {

        public static void main (String[] args) {
            //Start the game
            startGame();

        }

        private static void startGame() {

            //Declares
            GameHandler handler = new GameHandler();
            Scanner console = new Scanner(System.in);   
            boolean game = true;
            String input = "";  

            //Print program welcome text
            handler.printStart();

            //While in game...
            while (game) {
                //Getting input ready for new commands from the player
                input = console.nextLine();

                //Checking if input was set.
                if (input != null) {
                    //Selecting the game you want to play.
                    handler.selectGame(input);

                    //If game was selected.. then.. let's start playing.
                    while (handler.inGame) {
                        //Use will say something.
                        input = console.nextLine();

                        //If it was "exit", it will go back and select another game.
                        if (input.equals("exit")) {
                            handler.exitGame();
                        } else {
                            //Play again.
                            handler.continueGame(input);
                        }
                    }
                }
            }
        }
    }

GameHandler.java:

```
package games;
import java.io.*;

public class GameHandler {

private String[] games = {"Spin", "Tof"};
private String[] navigation = {"Back", "Start"};
private Spin spin = new Spin();
private boolean spinGame = false;
private boolean tofGame = false;

i would suggest to change

private boolean inArray(String value) {
        int returning = 0;
        for (String s : games) {
            if (value.equalsIgnoreCase(s)) {
                returning = 1;
            }
        }
        if (returning == 1) {
            return true;
        } else {
            return false;
        }
    }

to

private boolean inArray(String value) {
        boolean doesExist = false;
        for (String s : games) {
            if (value.equalsIgnoreCase(s)) {
                doesExist = true;
                break;
            }
        }
        return doesExist;
    }

To OP : Pretty impressive improvement since then.

Put this

public class GameHandler {

    private String[] games = {"Spin", "Tof"};
    private String[] navigation = {"Back", "Start"};
    private Spin spin = new Spin();
    private boolean spinGame = false;
    private boolean tofGame = false;
    public boolean inGame = false;

into the GameHandler constructor, it is a convention to define non-static variable in the class constructor.

You have a massive error in your Spin class. you have declared private int auth = this.rand(1000) / 5;. So do you know how this keyword works? i don't think so, after running your new code and judge it by the previous i think that you only try break your huge code into smaller part without thinking the logic how it will be executed. I will recommend you to at first do some basic Java programming with small classes and methods and you should start with the official tutorial. Good Luck.
