Compiler warning with Annotations/Generics

[Ra Carter]

I am getting compiler warnings in the following code

  
public static void main(String[] args)
{
//get all the classes in a package
Class[] myClasses = getClasses(PACKAGE_NAME);

//display annotation data from Classes with MyAnnotation
for(Class c : cfClasses)
{
//compiler warning on next line that says:
//Type safety: The method isAnnotationPresent(Class) belongs 
//to the raw type Class. References to generic type Class<T> 
//should be parameterized
if(c.isAnnotationPresent(MyAnnotation.class))
{
//similar warning at this next line:
//Type safety: The method 
//getAnnotation(Class) belongs to the raw 
//type Class. References to generic type 
//Class<T> should be parameterized
MyAnnotation classDetails = (MYAnnotation)c.getAnnotation(MyAnnotation.class);
System.out.println(c.toString() + " details:");
System.out.println("Name = " + classDetails.name());
System.out.println("Author = " + classDetails.author());
//etc.

Can someone explain what these warnings mean to me and how to correct them?

What do I see the following compiler warning?
Note: <something>.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
