试图理解java中的类继承

public class SuperSub {
  public void overideThisMethod(){
    System.out.println("Printed from Superclass");
  }
}

我有一个像这样的子类,

public class SubClass2 extends SuperSub { 
  @Override
  public void overideThisMethod(){
    System.out.println("from subclass2");
  }
  public static void main(String[] args){
    SubClass2 subClass2= new SubClass2();
    subClass2.overideThisMethod();
    SuperSub superSub = new SuperSub();
    superSub.overideThisMethod();
  }
}

我从运行程序时得到输出：

run:
from subclass2
Printed from Superclass

输出不应该是,

run:
from subclass2
from subclass2

非常感谢任何澄清,谢谢！
