Java Syntax - class

[Jenny]

Hi,

In the code below, what is class in
Applet.newAudioClip(Test1.class.getResource("ladieu.wav")).play()? I
could not such property in Object class. Thanks.

import java.applet.*;
public class Test1 {
public static void main(String args[]) {
Applet.newAudioClip(Test1.class.getResource("ladieu.wav")).play();
}
}

It's syntactic sugar for the compiler - not a "real" variable. In
effect, it does the same as Class.forName("Test1").

It is the so-called class literal.
Loosely speaking you can think of it as a static variable implicitly
declared like
public final static Class class = ...;
in every Java class.
For the exact definition see

Test1.class is a read-only property that refers to the Class object
representing the Test1 class.
