Using a method to search a match in a list in Java

Question

I am trying to create a program that will get input from a user using a package called 'bulletproof' (done, works fine) but I am getting an infinite loop error when I find a match. I am a bit over my head and I do not feel I quite comprehend why my code is not working. I am not looking for a direct answer as I am trying to learn this, but any help would be sincerely appreciated. Thank you, my code is as follows.

--edit-- i got the program working. Thank you all for your help, you folks are tremendous.

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;
}  

}

I think easiest way to do is -

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;
}
