Java makes a simple volleyball game scoring system

This article mainly introduces Java to implement the volleyball game scoring system in detail, which has certain reference value. Interested friends can refer to it

Preliminary plan:

Perhaps due to personal reasons, the volleyball scoring system was completed during the holiday. I haven’t written a blog yet. I just kept pushing it but didn’t want to write. I also started working after the Chinese New Year. Maybe I just started working as an intern. Tight so I waited until now.

Before writing this system, I briefly conceived it. Because I went to Luoyang to participate in Java training for more than a month before leaving school, so the IDE I used to write the project was a Java environment. At first, I considered using jsp for the interface, and architecture using mvc, but then I thought the workload was too much and the effect was not very good. Finally, pure Java code was written and displayed on the virtual machine.

Requirement analysis:

The volleyball competition is a best-of-five game system. The team that scores 25 points in each game and leads the opponent by more than 2 points will win one game. Victory, the first team to win three rounds will win the game. If the score is 24:24 during the game, one side must lead the other side by 2 points to end the round. If the score of the first four games between the two sides is 2:2, the fifth game will be played. The team that scores 15 points in the fifth game and leads the opponent by more than 2 points will win. If the score is 14:14 during the game, one side must lead the other side by 2 points to end the game.

User example:

Code design:

package ss;
 
import java.util.Scanner;
/**
 * 排球计分系统
 *
 * 使用排球计分系统可以进行简单的排球计分操作以及查询某一局的比分。
 * 1、比赛总共5局，每一局5分，若是有一方领先对方3分，则视为这一方胜利。
 * 5局结束后，统计两方胜利的次数，输出最终胜利的一方。并退出程序
 * 2、使用查询功能可以查询过往的比赛成绩，输出比分和胜利的一方

Summary: Since I didn’t learn Java for a long time, I encountered some problems when writing this project, but they were solved in the end. , because I have learned C#, the basics of the two are relatively similar, and it doesn’t take a lot of time. Since time is tight and the company is working on a project, I may not have enough time as in school, but I will definitely take it seriously.
