两个操作如何在if-else if语句中？

Question

我正在努力制作一个简单的足球模拟计划,但我有一个相互匹配的问题.if语句在找到一个条件后退出循环.但我想做两个条件和两个操作.可能吗？

package soccer.simulator;
import java.util.Random;

public class SoccerSimulator {
    /**

    public static void main(String[] args) {
        int HomeTeamScore = 0;
        int AwayTeamScore = 0;
        Random randomGenerator = new Random();

        String HomeTeam = new String();
        String AwayTeam = new String();
        int HomeTeamID = randomGenerator.nextInt(10);
        int AwayTeamID = randomGenerator.nextInt(10);

        if(HomeTeamID == AwayTeamID){
            while (HomeTeamID != AwayTeamID){
                AwayTeamID = randomGenerator.nextInt(10);
            }
        }

        if(HomeTeamID == 0 || AwayTeamID == 0){

                AwayTeam = "Barcelona";
            }
        } else if(HomeTeamID == 2 || AwayTeamID == 2){
            if(HomeTeamID == 2){
                HomeTeam = "Bayern Munich";
            }else{
                AwayTeam = "Bayern Munich";
            }
        } else if(HomeTeamID == 3 || AwayTeamID == 3){
            if(HomeTeamID == 3){
                HomeTeam = "Chelsea";
            }else{
                AwayTeam = "Chelsea";
            }
        } else if(HomeTeamID == 4 || AwayTeamID == 4){
            if(HomeTeamID == 4){
                HomeTeam = "Borussia Dortmund";
            }else{
                AwayTeam = "Borussia Dortmund";
            }
        } else if(HomeTeamID == 5 || AwayTeamID == 5){
            if(HomeTeamID == 5){
                HomeTeam = "Galatasaray";
            }else{
                AwayTeam = "Galatasaray";
            }
        } else if(HomeTeamID == 6 || AwayTeamID == 6){
            if(HomeTeamID == 6){
                HomeTeam = "Juventus";
            }else{
                AwayTeam = "Juventus";
            }
        } else if(HomeTeamID == 7 || AwayTeamID == 7){
            if(HomeTeamID == 7){
                HomeTeam = "Manchester United";
            }else{
                AwayTeam = "Manchester United";
            }
        } else if(HomeTeamID == 8 || AwayTeamID == 8){
            if(HomeTeamID == 8){
                HomeTeam = "Milan";
            }else{
                AwayTeam = "Milan";
            }
        } else if(HomeTeamID == 9 || AwayTeamID == 9){
            if(HomeTeamID == 9){
                HomeTeam = "Real Madrid";
            }else{
                AwayTeam = "Real Madrid";
            }
        }

        //Generating each random integers in range 0..99 for 90 minutes
        for(int minutes = 0; minutes <= 90; minutes++){
            int randomInt = randomGenerator.nextInt(100);

            //if random int equals 0,1,2 home team scores
            if(randomInt < 3){ HomeTeamScore = HomeTeamScore + 1; }

            //if random int equals 98,99 away team scores
            //home team has 1 more int because playing at home is better
            if(randomInt > 97){ AwayTeamScore = AwayTeamScore + 1; }                         
        }
        System.out.println ("Simulation for match of the week:");
        System.out.println (HomeTeam + " " + HomeTeamScore + " - " + AwayTeamScore + " " + AwayTeam);

        }   
    }

输出是: 3 - 1 Arsenal

要么: Arsenal 2 - 1

Answer 1

您只设置一个团队名称,因为根本没有循环,在您的巨大if-else声明中只有一个最终条件成立.一种更简单的方法(并且非常值得推荐,以便在不久的将来为其他任何会触及您的代码的人保持理智)将您的团队名称存储在一个数组中.-

String[] teamNames = new String[] {"Arsenal", "Barcelona", "Bayern Munich", "Chelsea", "Borussia Dortmund", "Galatasaray", "Juventus", "Manchester United", "Milan", "Real Madrid"};

然后替换整个if-else.-

HomeTeam = teamNames[HomeTeamID];
AwayTeam = teamNames[AwayTeamID];

作为一个侧面说明,你应该坚持Java约定的变量命名,并使用小写驼峰(homeTeam,awayTeam,homeTeamID,awayTeamId).
