testinout1.java

用java编写的一些初级代码

//内部类被外部调用
class Outer
{
    int out_i=1;
    class Inner
    {
	void display(){
	    System.out.println("out_i is " +Outer.this.out_i);
	}
    }
}
public class testInout1
{
    public static void main (String [] args)
    {
	Outer oer=new Outer();
	Outer.Inner ii=oer.new Inner();
	ii.display();
    }
}
