[英]Both the if statement and the else if statements run
我是java编程的新手，并且一直致力于各种各样的刽子手游戏。 这是我的导师提出的练习，在完成基本版本之后，我想制作一个更先进的练习。 到目前为止，我发现代码中的问题是if语句和else if语句都运行。 为了解决这个问题，我添加了一些break语句。 它确实帮助解决了一个问题但两个语句仍在运行。
这是if else语句错误：
if (guess.equals(letters[i])){
wordi[i] = guess.charAt(i);
System.out.println("Included");
break;
}
else if (!guess.equals(letters[i])){
wordi[i] = '*';
wrong_guess++;
num_guess ++;
System.out.println("Not included");
break;
如果它有帮助，这是完整的代码：
import java.util.Scanner;
public class Test {
public static Scanner input = new Scanner(System.in);
@SuppressWarnings({ "unused" })
public static void main(String[] args) {
String[] words = new String[10];
words[0] = "chair";
words[1] = "apple";

words[3] = "word";
words[4] = "table";
words[5] = "cow";
words[6] = "cabbage";
words[7] = "food";
words[8] = "computer";
words[9] = "mouse";
int cap_guess = 6;
int wrong_guess = 0;
int n = (int)(Math.random()*10);
String word = words[n];
String out_word = "";
int num_guess = 1;
for(int count = 0; count < word.length(); count ++){
out_word += "*";
}
boolean success = false;
String guess = "";
String[] letters = new String[word.length()];
for (int i = 0; i < letters.length; i++){
letters[i] = word.substring(i,i+1);
System.out.println(letters[i]);
}
while (num_guess <= cap_guess){
display(wrong_guess);
System.out.println(out_word);
System.out.print("Enter a guess: ");
guess = input.nextLine();
guess = guess.trim();

System.out.println("Guess: " + guess);
char[] wordi = out_word.toCharArray();
if (guess.length() == 1){

在此先感谢您的帮助。
问题是你的break 。 你没有迭代for循环，你总是打破
for (int i = 0; i < word.length(); i++){
boolean found = false;
if (guess.equals(letters[i])){
wordi[i] = guess.charAt(i);
System.out.println("Included");
found = true;
}
else if (!guess.equals(letters[i])){
wordi[i] = '*';
}
}
if (!found)
wrong_guess++;
num_guess++;
我没有测试但应该没问题
我稍稍清理了你的主要部分，但是我会把一些工作留给你。 您应该将单词列表初始化之类的内容包装到自己的方法中。 实际上，通常建议通常建议将任何可以剥离到自己方法中的代码块。 我不认为你必须走这么极端，但据说你永远不应该有超过8行的方法。 有点武断，但重点是像while循环中发生的事情可以放入自己的方法中。 如果您可以将一段代码描述为执行单个任务，则应将其置于自己的方法中。 这也将在调试时帮助您，因为所有内容都模块化为执行特定任务的代码块。 很容易分辨出问题所在，因为在对所有内容进行适当分解时，代码应仅存在于相关的范围内。 以单词数组初始化为例，这会占用整个垂直空间，与获取用户输入，验证用户输入，显示结果等无关。如果您正在调试某些功能，可能会让人感到困惑。查看与它无关的代码。
