开关未执行
[英]Switch not executing
问题描述
我不确定是否曾问过这个问题或与之类似的问题，但我进行了搜索，但一无所获。 我刚刚在学校开始编程，但是老师的项目给了我们，我可以很快完成，而且有点太简单了，所以我开始研究Oracle的Java教程。 经过大量的实验，我决定制作一个基于MGSV TPP的基于文本的隐形游戏。 无论如何，这已经足够了。 我的问题是代码中的开关没有执行。 娜达 我已经一遍又一遍地查看我的代码，但是我不能出什么问题。 这是我第一次使用开关。 这是带有开关的代码片段：
public void shoot() {
Random rand = new Random();
String farshot = this.shoot[rand.nextInt(this.shoot.length)];
if(reload == 1) {
if(supressor > 1) {
if(dbme<=75) {
System.out.println("Great Job! He's out cold!");
if(dbme == Guard1)
Guard1 = 0;
else if(dbme == Guard2)
Guard2 = 0;
else if(dbme == Guard3)
Guard4 = 0;
else if(dbme == Guard4)
Guard4 = 0;

else if(dbme == Guard8)
Guard8 = 0;
dbme = 0;

supressor--;
}
} else { System.out.println("You're suppressor had worn out! You alerted the guards! But Great shot, you knocked him out!");

在代码的顶部，您声明了字符串数组，但每个数组仅包含一个字符串：
String[] objects = {"Food, Water, Ammo, Suppressor, Mags"};
String[] shoot = {"miss, headshot, alert"};
因此，当您初始化farshot变量时
String farshot = this.shoot[rand.nextInt(this.shoot.length)];
它将始终包含值miss, headshot, alert 。 这与您要测试的任何情况都不匹配。
我假设您要执行以下操作：
String[] objects = {"Food", "Water", "Ammo", "Suppressor", "Mags"};
String[] shoot = {"miss", "headshot", "alert"};
不知道它是否可以解决您的所有问题，但这只是一个开始。
switch 语句未正确执行
