outer.java

接着上次传入一些Java学习中的实验

public  class Outer{
	private int size;
    public  class Inner{
	private int counter=10;
	private   int doStuff(){return size++;}
	   					}
 public void doTest(){
	Inner inner=new Inner();
	
	int s=inner.doStuff();
	System.out.println(size);
	System.out.println(s);
	System.out.println(inner.counter);
    //System.out.println(counter);//编译错误
    
     }
public static void main(String args[]){
//	Inner in=new Inner();
	 
	Outer o=new Outer();
	System.out.println();//编译错误
	o.doTest();
	}
      }
