Question

在包1中，我有Mainclass和SubClass。如果在包2中如何访问子类？

如果我们想要访问同一个包但不同文件Java的子类，我们可以使用如下：

  package Modifier;

        public class Other {
        public static void main(String[] args) {
            Public ut =  new Public();
     // Access the subclass of a class in the same package different file
            Public.subPublic sub_ut = ut.new subPublic();
        sub_ut();
        }
    }

但是如何在不同的Package中访问Class的子类？感谢...

我认为这没有意义，但如果你想这样做。检查你的访问修饰符，你必须使用public：

 <button id="myBtn" class="btn btn-primary" type="button" data-toggle="collapse" data-target="#collapseExample" aria-expanded="false" aria-controls="collapseExample">
    Button 
  </button>

<div class="collapse" id="collapseExample">
  <div class="card card-body">

Answer 2

内部类访问与访问字段或方法没有什么不同。您可以为内部类使用public，protected，package或private访问修饰符。

如何访问不同包中的子类？
