java内部类

public class Text01 {

 public static void main(String[] args) {
  // TODO Auto-generated method stub
  //创建 外部类对象,第一种写法
  Neibu01 neibu01=new Neibu01();
  Neibu02 neibu02=neibu01.new Neibu02();
  //第二种写法
  Neibu02 neibu_02=new Neibu01().new Neibu02();
  neibu02.shwo();
 }

}

局部内部类定义：在一个类中方法里声明一个类

public class Outer {
 private String name="absc";
 private int age=18;
 public void show() {
  String address="南京";
  
  class Inner{
   private String phone="15542665398";
   public void show2() {
    System.out.println(name);
    System.out.println(Outer.this.age);
    System.out.println(address);
    System.out.println(this.phone);
   }
  }
  Inner inner=new Inner();
  inner.show2();
 }
}
