Automatic code upgrade to Java 5

Question

I have a lot of Java 1.4 code on which I am switching to Java 5. I would like to fix all the compiler warnings about using raw types in parameterized classes, and I am wondering if there is a tool that can automatically transform something like:

List myList = new ArrayList();
myList.add("foo");
String foo = (String) myList.get(0);

at

List<String> myList = new ArrayList<String>();
myList.add("foo");
String foo = myList.get(0);

I understand that Generics are quite complex and therefore do not expect such a tool to be able to select the most correct parameterized type in all cases. However, if it can handle simple cases (like above) and won't break my code, I will be satisfied.

Similarly, I would like to change all the old-skool loops to a simplified loop introduced in Java 5.

Is there such a tool?
