非靜態的成員變量，調用順序為

1、外部類實例化：outer out=new outer() ;

2、在靜態內部類調用：int i=out.i ;

或者1 2步直接合并：int i=new outer().i ;

public?class?Outer{
????private?String?name="zhangsan";
????public?static?Inner{
????????public?void?show(){
????????????System.out.print(new?Outer().name);
????????????Outer?o?=?new?Outer();
????????????System.out.print(o.name);
????????}
????????
????}
}
