public static void main(String[] args) throws Exception{
ClassTest test=new ClassTest();
ClassTest test1=test.getClass().newInstance();
test1=test;
test.printMessage();
test1.printMessage();
System.out.println(test.hashCode());
System.out.println(test1.hashCode());
Method[] method=test1.getClass().getMethods();
for(Method m :method){
System.out.println(m.getDeclaringClass());
System.out.println(m.getName());
