求大大编写一段java程序...万分感谢！

本人java 0基础..最近在看视频自学，但是被要求要编以下这样一个程序，完全超出了我自学的进度...很快就要交了..实在没办法只能来这里求助了，希望有大神能帮忙，谢谢_(:з」∠)_...
要求大致如下：

编写一个程序，形成一个”anagram puzzle“（字谜拼图）程序。”anagram“指由颠倒字母顺序而构成的字，一个能被其他词或短语中的字母转换或重组而形成的词或短语。例如，”CHARM“是”MARCH“的anagram，”CLINT EASTWOOD“是”OLD WEST ACTION“的anagram。 这个程序中只考虑单词的anagram。同时在制作这个拼图的内容中，anaram的定义是”一个单词能被一个字符串的字母转换形成（它可以是也可以不是一个单词）这个程序需要编的举例来说：
CHARM和MARCH都是字符串RMCHA的anagram。在这例子中RMCHA是一个anagram puzzle，然后MARCH和CHARM都是它的解决方案。所以更具体化来说这个程序的目标是：随机选择一些英语单词，并输出一个它的随机重排字母。
你需要一个单词列表文件，wordlist.txt或stateslist.txt，（这个我上传不了。。大致程序能编出意思就行了，谢谢）运行大型字典单词表，输入：
Java anagrampuzzlegenerator wordlist.txt

另外原题给了个可能是提示或者是例子的，如下：

class Echo {
public static void main(String[] args) throws FileNotFoundException {
Scanner in = new Scanner(new FileInputStream(args[0]));

int size = in.nextInt();//first item is the number of words

//while loop print out of words in file
int i = 0;
while ( i < size ) {
System.out.println(in.next());
i++;
}

}
}

能简单讲解一下最好，不苛求...关键只要能编出大致意思就行了，万分感谢_(:з」∠)_
