Ball Game example In Java

In this example, i have shown you an example which have mainly three classes:
BallGame.java
BallGameImpl.java
App.java
What does this game does?
In this game, you will fill the no. of players and no. of balls. Then this game will distribute these balls among the players. After distribution it will tell how many balls each player have and how many balls are left. 
 
BallGame.java 
package ballgame;
public class BallGame {
            private Integer ballCount;
            private Integer playerCount;
           public BallGame() {
           }
           public Integer getBallCount() {
                    return ballCount;
            }
          public void setBallCount(Integer ballCount) {
           this.ballCount = ballCount;
            }
            public Integer getPlayerCount() {
            return playerCount;
           }
          public void setPlayerCount(Integer playerCount) {
           this.playerCount = playerCount;
           }
}
 
BallGameImpl.java
package ballgame;
public class BallGameImpl {
private BallGame ballGame;
public BallGameImpl(BallGame ballGame) {
 this.ballGame = ballGame;
}
public Integer calculateRemainingBallCount() {
 Integer remainingBallCount = this.ballGame.getBallCount() % this.ballGame.getPlayerCount();
 return remainingBallCount;
}
public Integer calculateEqualityDistributedBall() {
 Integer distributedBalls = this.ballGame.getBallCount() / this.ballGame.getPlayerCount();
 return distributedBalls;
}
}

App.java to start this game.
package ballgame;
public class App {
public static void main(String[] args) {
 BallGame ballGame = new BallGame();
 ballGame.setBallCount(34);
 ;
 ballGame.setPlayerCount(5);
 BallGameImpl ballGameImpl = new BallGameImpl(ballGame);
 System.out.println(ballGameImpl.calculateRemainingBallCount());
 System.out.println(ballGameImpl.calculateEqualityDistributedBall());
}
}
 
 
I hope you enjoyed this example. If having any doubts ask me in comments.
