Class/InnerClass

昨天工作中提到了多个class写在一个文件的方式，写了个例子，记录一下这种情况下各类的调用方式。

 

package test;

public class MultiClassesTest {
 
 public static class InnerClass {

  @Override
  public String toString() {
   return super.toString() + " and my own toString result is \"xixi\"";
  }
  
 }
 
 public class InnerClass2 {

  @Override
  public String toString() {
   return super.toString() + " and my own toString result is \"qiqi\"";
  }
  
 }
 
 public static void main(String[] args) {
  TheOtherClass to = new TheOtherClass();
  System.out.println(to.toString());
  MultiClassesTest mt = new MultiClassesTest();
  System.out.println(mt.toString());
  InnerClass ic = new InnerClass();
  System.out.println(ic.toString());
  InnerClass2 ic2 = new MultiClassesTest().new InnerClass2();
  System.out.println(ic2.toString());
 }

 @Override
 public String toString() {
  return super.toString() + " and my own toString result is \"hehe\"";
 }

}

class TheOtherClass {

 public static void main(String[] args) {
  MultiClassesTest mt = new MultiClassesTest();
  System.out.println(mt.toString());
  TheOtherClass to = new TheOtherClass();
  System.out.println(to.toString());
  MultiClassesTest.InnerClass ic = new MultiClassesTest.InnerClass();
  System.out.println(ic.toString());
  MultiClassesTest.InnerClass2 ic2 = new MultiClassesTest().new InnerClass2();
  System.out.println(ic2.toString());
 }

 @Override
 public String toString() {
  return super.toString() + " and my own toString result is \"haha\"";
 }

}

编译及运行结果：

E:\TestProject>javac test/MultiClassesTest.java

E:\TestProject>java test.MultiClassesTest
test.TheOtherClass@61de33 and my own toString result is "haha"
test.MultiClassesTest@14318bb and my own toString result is "hehe"
test.MultiClassesTest$InnerClass@ca0b6 and my own toString result is "xixi"
test.MultiClassesTest$InnerClass2@10b30a7 and my own toString result is "qiqi"

E:\TestProject>java test.TheOtherClass
test.MultiClassesTest@61de33 and my own toString result is "hehe"
