JAVA  STRING ANAGRAM PROGRAM

/*
Exercise: 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 ine string
is an anagram of another string.
The Program should ignore white space and punctuation.
