Difference between two files

Hi, I need to find difference between two files.

This is an example:

oldfile.txt:

This is the old file.

Ineed some help with

this task!.

newfile.txt:

This is the new file.

I need help with this task please!.

Differences:

* old -> new

*need -> need

* "some" was deleted

* please was added

Notice that I don't care spaces, new lines or tabs.

The code should looks like:

enum DifferenceType{ Added, Deleted, Replaced};

class DiffText{

public String Text;

public DifferenceType Type;

public String ReplacedText;

};

//...

Diff d =new Diff("oldfile.txt","newfile.txt");

while(!d.end()){

DiffText dtext = d.getNext();

String s ="";

switch(s.Type){

case Added:System.out.println(s.Text +" ~ added");

case Deleted:System.out.println(s.Text +" ~ deleted");

case Replaced: System.out.println(s.Text +" replaced by " + s.ReplacedText);

}

}

Thanks for your help in advance.
