How to find if a method returns void?

Normally this is the question which comes when using reflection to find the return type of a method. Void class comes to rescue.

   public class VoidClassApp {
       public static void main(String[] args) throws NoSuchMethodException {
          Class clazz = Test.class.getMethod("method").getReturnType();
          System.out.println(clazz == Void.TYPE);

   class Test {
      public void method() {
         System.out.println("Does Nothing");

The output is : true
