Ive had some trouble making this program work out.

Write an original Java program to parse the words from a long String. The Java library offers similar functonality within its tokenizer classes, but you should not use those for this assignment. Hand in one Java class called SentenceParser. Yor class should be able to break the given sentnece into words, where word is defined as the characters between any spaces, commas, or periods. The class should have a constructor that takes a sentence as a parameter. The class should define several public value methods. The class should have one method called "public static void main ()" that demonstrates what your class can do with the specific hard-coded sentence shown below. The demonstration should write this text to the console:

The quick brown fox jumped over the lazy dog.

This is the code we've been provided to help us. My professor doesnt want us to use any sort of Java shortcuts in this program either. Any help is appriciated.
