java - 使用方法在 Java 列表中搜索匹配项

Question

我正在尝试创建一个程序，该程序将使用名为“bulletproof”的程序包从用户那里获取输入(已完成，工作正常)，但是当我找到匹配项时出现无限循环错误。我有点不知所措，我觉得我不太理解为什么我的代码不起作用。我不是在寻找直接的答案，因为我正在努力学习这个，但我们将不胜感激任何帮助。谢谢，我的代码如下。

--编辑--我让程序工作了。谢谢大家的帮助，你们太棒了。

import bulletproof.*;

public class A26_1 {
public static void main(String[] args) {
    BPScanner kb = new BPScanner();
    String reservedWordToCheck = kb.getStringFromUser("Enter a word to see if it's reserved or enter leave: ");

    System.out.println(ReservedWordChecker(reservedWordToCheck));
}

public static String ReservedWordChecker(String reservedWordToCheck) {
    String[] table = {
            "abstract", "assert", "boolean", "break", "byte", "case", "catch", "char", "class", "const",
            "continue", "default", "do", "double", "enum", "extends", "final", "finally", "float",
            "for", "goto", "if", "implements", "import", "instanceof", "int", "interface", "long", "native",
            "new", "package", "private", "protected", "public", "return", "short", "static", "strictfp", "super",
            "switch", "synchronized", "this", "throw", "throws", "transient", "try", "void", "volatile", "while"
        };

    while (true) {                      
        if (reservedWordToCheck.equalsIgnoreCase("leave"))
            break;                
        boolean found = false;

        for (int i=0; i < table.length; i++) {
            if (reservedWordToCheck.equalsIgnoreCase(table[i])) {
                found = true;
                break;
            }               
            if (found)
                System.out.println("Yeah, " + reservedWordToCheck + ", is reserved as a Java identifier.");
            else
                System.out.println("Nope, the word " + reservedWordToCheck + ", isn't reserved. Go hog wild.");                      
        }      
        System.out.println("OK BYE");
    } return reservedWordToCheck;
}

我认为最简单的方法是 -

public static boolean ReservedWordChecker(String reservedWordToCheck) {
    String[] table = {
            "abstract", "assert", "boolean", "break", "byte", "case", "catch", "char", "class", "const",
            "continue", "default", "do", "double", "enum", "extends", "final", "finally", "float",
            "for", "goto", "if", "implements", "import", "instanceof", "int", "interface", "long", "native",
            "new", "package", "private", "protected", "public", "return", "short", "static", "strictfp", "super",
            "switch", "synchronized", "this", "throw", "throws", "transient", "try", "void", "volatile", "while"
        };

       for (String data : table) {
            if (reservedWordToCheck.equalsIgnoreCase(data)) {
                return true;
            }
        }
      return false;
}
