Unnecessary type casts

Hello!

Is it possible to use checkstyle to detect unnecessary type casts in java?

Let me show two examples:

 

Ex 1:

String helloString = (String) getHelloString();

 

public String getHelloString() {

  return "hello";

}

 

--

 

Ex 2:

List aList = (List) getNewList();

 

public ArrayList getNewList() {

  return new ArrayList();

}

 

As you can see the casts (String) and (List) are not necessary. 

 

I need this for a project going from java 1.4 to 1.5 where typecasts are no
longer necessary as generics become available.
