字符数组需要按照一定的顺序和位置显示

Question

试图让这个游戏的最后部分工作。它是一个hang子手游戏，我只需要它显示正确的猜测他们在这个词。

这是当一个正确的猜测给出

else 
      { 
       int alreadyGuessed = guesses.indexOf(guess); 
       if (alreadyGuessed == -1) 
       { 

        guesses = guesses + guess + ""; 
        jlbWord.setText("Word: " + charWord[currentGuess]); 
       } 
       else{} 

      } 

现在它只是显示出每个字母的代码片段。我也可以设置它，因此它会显示每个输入的内容，但不是按照正确的顺序排列，这使得用户更难以猜出该单词是什么。

Y。

你应该重构你的代码，并保留在TreeSet<Character>数据结构的猜测。它确保每个字符只存储一次，迭代器按照升序返回所有存储的字符。

段：

Set<Character> guesses = new HashSet<Character>(); 

// add a guess 
guesses.add('e'); 
guesses.add('r'); 
guesses.add('a'); 
guesses.add('e'); // will not be added, already in the set 

// test 
if (guesses.contains('e')) { ... } 

// test if a word is "guessed" 
boolean foundIt = true; 
for (char c:word.toCharArray()) { 
    if (!guesses.contains(c)) { 
     foundIt = false; 
     break; 
    } 
} 
// foundIt is true if all chars of word have been guessed 

// print 
for (char c:guesses) 
    System.out.print(c); // prints: aer
