innertest.java

Java 2实用编程百例,一些比较实用的J2SE小程序,可以通过这些程序熟悉JAVA基础知识

package ch01.section05;

public class InnerTest {
  //两个内部类
  class Inner1 {
    //内部类的构造方法
    public Inner1() {
      System.out.println("我是一个内部类");
    }
  }

  class Inner2 {
    private String tag;
    Inner2(String str) {
      tag = str;
      System.out.println(readtag());
    }

    String readtag() {
      return tag;
    }
  }

  public void ship(String str) {
    Inner1 a = new Inner1();
    Inner2 b = new Inner2(str);
  }

  public static void main(String[] args) {
    InnerTest p = new InnerTest();
    p.ship("内部类的使用");
    InheritTest1 Inherit1 = new InheritTest1();
    Inherit1.play();
    System.out.println(Inherit1.what());
    InheritTest2 Inherit2 = new InheritTest2();
    Inherit2.play();
    System.out.println(Inherit2.what());

  }
