Java的java.lang.Void和void的区别

Void a = null;

public final
class Void {

    /**
     * The {@code Class} object representing the pseudo-type corresponding to
     * the keyword {@code void}.
     */
    @SuppressWarnings("unchecked")
    public static final Class<Void> TYPE = (Class<Void>) Class.getPrimitiveClass("void");

    /*
     * The Void class cannot be instantiated.
     */
    private Void() {}
}

 Void function(int a, int b) {
    //do something
    return null;
 }

public class Test {
    public void print(String v) {}

    public static void main(String args[]){
        for(Method method : Test.class.getMethods()) {
            if(method.getReturnType().equals(Void.TYPE)) {
                System.out.println(method.getName());
            }
        }
    }
}
