[英]Both the if statement and the else if statements run
我是java編程的新手，並且一直致力於各種各樣的劊子手游戲。 這是我的導師提出的練習，在完成基本版本之后，我想制作一個更先進的練習。 到目前為止，我發現代碼中的問題是if語句和else if語句都運行。 為了解決這個問題，我添加了一些break語句。 它確實幫助解決了一個問題但兩個語句仍在運行。
這是if else語句錯誤：
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;
如果它有幫助，這是完整的代碼：
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[2] = "bear";
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();
guess = guess.toLowerCase();
System.out.println("Guess: " + guess);
char[] wordi = out_word.toCharArray();
if (guess.length() == 1){
for (int i = 0; i < word.length(); i++){
if (guess.equals(letters[i])){

break;
}

System.out.println("Not included");

}
/*System.out.println(word);

在此先感謝您的幫助。
問題是你的break 。 你沒有迭代for循環，你總是打破
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++;
我沒有測試但應該沒問題
我稍稍清理了你的主要部分，但是我會把一些工作留給你。 您應該將單詞列表初始化之類的內容包裝到自己的方法中。 實際上，通常建議通常建議將任何可以剝離到自己方法中的代碼塊。 我不認為你必須走這么極端，但據說你永遠不應該有超過8行的方法。 有點武斷，但重點是像while循環中發生的事情可以放入自己的方法中。 如果您可以將一段代碼描述為執行單個任務，則應將其置於自己的方法中。 這也將在調試時幫助您，因為所有內容都模塊化為執行特定任務的代碼塊。 很容易分辨出問題所在，因為在對所有內容進行適當分解時，代碼應僅存在於相關的范圍內。 以單詞數組初始化為例，這會占用整個垂直空間，與獲取用戶輸入，驗證用戶輸入，顯示結果等無關。如果您正在調試某些功能，可能會讓人感到困惑。查看與它無關的代碼。

如何讓我的 if 語句在 if-else 語句運行時再次運行？

多個else / if語句的目的？ 如果不是else語句，則不是一個
[英]purpose of multiple else/if statements? NOT single if then else statement
