//4. For obj.hashCode()
    public static int hashCodeForCC(Object obj) {

//5. For getModifiers()

    }

//6. For public native boolean isInstance(Object obj);we can use keyword instanceof replace it.

//7. For Thread.sleep(5000L);
  TimeUnit.SECONDS.sleep(5);

//8.Thread.currentThread().getContextClassLoader()
  Class.getClassLoader();
