static - How to load nested classes in Java? -

i have following java code:

public class checkinnerstatic {  private static class test {     static {         system.out.println("static block initialized");     }     public test () {         system.out.println("constructor called");     } }      public static void main (string[] args) throws classnotfoundexception, instantiationexception, illegalaccessexception {         system.out.println("inside main");         class.forname("test");    // doesn't work, gives classnotfoundexception         //test test = new test();   // works fine     } } 

why doesn't class.forname("test") work here while next line works fine?

use outer$nested (regardless if nested class static or not)

public class checkinnerstatic {      private static class test {     static {         system.out.println("static block initialized");     }     public test () {         system.out.println("constructor called");     } }      public static void main (string[] args) throws classnotfoundexception, instantiationexception, illegalaccessexception {         system.out.println("inside main");         class<?> cls = class.forname("checkinnerstatic$test");         //test test = new test();     } }
