获取字节码的三种方式

public class ReflectDemo {

    public static void main(String[] args) throws ClassNotFoundException {

        Test test  = new Test();

        Class one = Test.class;

        Class two = test.getClass();

        Class three = Class.forName("reflect.test.Test");

        System.out.println(one);

        System.out.println(two);

        System.out.println(three);

        System.out.println(one==two);

        System.out.println(one==three);

        System.out.println(three==two);

    }

}
