Anagram Checker Explanation

Question

im a first year programmer and i was wondering what this code extract does. Its part of a main which does a check to see if 2 words are anagrams of one another. Im not fullly sure what this represents though.

    for(int x = 0; x < array.length; x++)
    {
        if(x == array.length-1)
        {
            array[x] = word1.substring(x);
        }
        else
        {
            array[x] = word1.substring(x, x+1);
        }
    }       
    for(int x = 0; x < array.length && isAnagram != false; x++)
    {
        aLetter = array[x];
        if(word2.indexOf(aLetter) != -1)
        {
            isAnagram = true;
        }
        else
        {
            isAnagram = false;
        }
        if(isAnagram == true)
        {
            word2 = word2.replaceFirst(aLetter, "");
        }
    }

Substring (x) and substirng (x,x+1) really! Dont know too much about whats going on there. — Chilli, Mar 01 '13 at 15:21

Loop 1:

Make array of letters in word1.

Loop 2:

Remove each letter from word2.
isAnagram starts true.
If any letter is not found then isAnagram is false.

At the end isAnagram should be true and word2 should be empty.
