JAVA:文字游戏查询

Question

各位程序员大家好!

到目前为止我有这个代码:

public class Levels {
int cLevel;

public void newGame() {
    boolean newGame = true;
    if (newGame) {
        cLevel = 1;

        List<String> list = new ArrayList<String>();

        try {
            BufferedReader bf = new BufferedReader(new FileReader(
                    "src/WordGuess/ReadFile/LevelFiles/Level_" + cLevel
                            + ".txt"));
            String cLine;
            while ((cLine = bf.readLine()) != null) {
                list.add(cLine);
            }
            String words[] = new String[list.size()];
            words = list.toArray(words);

            System.out
                    .println("These are your help letters so you can beat that level: "
                            + words[0]);

            for (int i = 1; i < words.length; i++) {
                char[] replaceChar = words[i].toCharArray();

                for (int x = 0; x < replaceChar.length; x++) {
                    replaceChar[x] = '*';
                }
                String replacement = new String(replaceChar);

                System.out.println("\f" + replacement);

            }

            System.out.println("\t Score: " + Score(0) + ";\t Lives: "
                    + Lives(5) + ";");

            System.out.println("\n Enter Word:");
            System.in.read();

        } catch (Exception e) {
            System.out
                    .println("Oh! Something went terribly wrong. A team of highly trained and koala-fied koalas have been dispatched to fix the problem. If you dont hear from them please restart this program.");
            e.printStackTrace();
        }
    }
}

private int Lives(int lives) {
    int wrongTries = 0;
    boolean correctWord;
    int counter = 0;

    String livesForm[] = new String[lives];

    // for (int i = 0; i == lives; i++) {
    // livesForm[i] = "♥";
    // }

    return lives;
}

private int Score(int score) {

    return score;
}}

所以我的查询如下。

我想将生命显示为心形符号，并仍保留其整数值以用于功能目的。因此，如我的代码示例所示，5 条生命由 5 颗心表示，但仍保持 int 生命值 5。如我的示例所示，我还尝试使用整数值“生命”大小的字符串数组，并将被心取代。据我运行代码，没有显示任何错误，所以我假设数组已填充，但我不知道如何在控制台中将数组显示为“Lives:♥♥♥♥♥”。

我尝试过常规:

System.out.println(livesForm[i]);

但它没有显示任何内容。我不知道我的问题是否已经完全清晰地表达出来了。如果你们中的任何人能给我建议或提示，我会很高兴。感谢您花时间回答这个问题!

为什么不:

public String getLivesAsString(int lives) {
    StringBuilder sb = new StringBuilder(lives);
    for(int i = 0; i < lives; i++) {
        sb.append("♥");
    }
    return sb.toString();
}

？

不确定为什么需要一个数组来显示由整数定义的一定数量的“♥”符号？
