反射之创建对象以及Hash值相等问题

问题:
new 类()，所创建的对象，每new一次都是一个新的对象。
那么通过反射newInstance()获得的对象，是同一个吗？

   @Test
   public void test03() throws InstantiationException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
       Class clsClass = Cls.class;
       Class clsClass2 = Cls.class;
       Class clsClass3 = Cls.class;
       Class clsClass4 = Cls.class;

       Cls instance = (Cls)clsClass.newInstance();
       System.out.println("instance:"+instance.hashCode());

       Cls instance2 = (Cls)clsClass2.newInstance();
       System.out.println("instance2:"+instance2.hashCode());
       if(instance == instance2){
           System.out.println("赋值前instance==instance2:true");
       }else{
           System.out.println("赋值前instance==instance2:false");
       }

       instance.setName("李四");
       System.out.println("instance:"+instance.hashCode());
       instance2.setName("王五");
       System.out.println("instance2:"+instance2.hashCode());
       if(instance == instance2){
           System.out.println("赋值后instance==instance2:true");
       }else{
           System.out.println("赋值后instance==instance2:false");
       }

       System.out.println("************************************");

       Cls instance3 = (Cls)clsClass3.newInstance();
       Cls instance4 = (Cls)clsClass4.newInstance();
       Cls instance42 = (Cls)clsClass4.newInstance();
       System.out.println("instance3:"+instance3.hashCode());
       System.out.println("instance4:"+instance4.hashCode());
       System.out.println("instance42:"+instance42.hashCode());

       if(instance4 == instance42){
           System.out.println("同一个Class对象instance4==instance42:true");
       }else{
           System.out.println("同一个Class对象instance4==instance42:false");
       }
   }
      
结果：
instance:6061
instance2:6061
赋值前instance==instance2:false
instance:49685123
instance2:55290359
赋值后instance==instance2:false
************************************
instance3:6061
instance4:6061
instance42:6061
同一个Class对象instance4==instance42:false
  

①通过反射n创建对象,和new 类()创建对象一样.每newInstance()一次都是新的对象.
②hash值相等,但是通过==判断,不是同一个对象.

遗留问题:一个对象,赋值前后,hash值变化了.为什么?
可能答案:同样的 hashcode 有多个对象,未实例化之前为了方便在内存中查找这些个对象使用了同样的hash值,实例化之后改变了hash值,就明显不一样了.
