An anagram is a word or a phrase made by transposing the letters of another word or phrase; for example, "parliament" is an anagram of "partial men," and "software" is an anagram of "swear oft." write a program that figures out whether one string is an anagram of another string. the program should ignore white space and punctuation.

Anagram

Explanation:

public class Anagram {

   public static boolean areAnagrams(String string1,

                                     String string2) {

       String workingCopy1 = removeJunk(string1);

       String workingCopy2 = removeJunk(string2);

    workingCopy1 = workingCopy1.toLowerCase();

    workingCopy2 = workingCopy2.toLowerCase();

    workingCopy1 = sort(workingCopy1);

    workingCopy2 = sort(workingCopy2);

       return workingCopy1.equals(workingCopy2);

   }

   protected static String removeJunk(String string) {

       int i, len = string.length();

       StringBuilder dest = new StringBuilder(len);

   char c;

    for (i = (len - 1); i >= 0; i--) {

        c = string.charAt(i);

        if (Character.isLetter(c)) {

         dest.append(c);

        }

    }

       return dest.toString();

   }

   protected static String sort(String string) {

    char[] charArray = string.toCharArray();

    java.util.Arrays.sort(charArray);

       return new String(charArray);

   }

   public static void main(String[] args) {

       String string1 = "Cosmo and Laine:";

       String string2 = "Maid, clean soon!";

       System.out.println();

       System.out.println("Testing whether the following "

                        + "strings are anagrams:");

       System.out.println("    String 1: " + string1);

       System.out.println("    String 2: " + string2);

       System.out.println();

       if (areAnagrams(string1, string2)) {

           System.out.println("They ARE anagrams!");

       } else {

           System.out.println("They are NOT anagrams!");

       }

       System.out.println();

   }

}

because you most likely sighned up

what? ? i don't get it
