如果像以下怎么才能調用
public class HelloWorld {
public class Outer{
private int a=99;
public class Inner{
int b=2;
public void test(){
System.out.println("訪問外部類中的a："+a);
System.out.println("訪問內部類中的b："+b);
}
}
}
public static void main(String[] args) {
HelloWorld g=new HelloWorld();
Outer h=g.new Outer();
Outer.Inner j=g.h.new Outer.Inner();
h.test();
}
}

public?class?HelloWorld?{ ????????private?int?a=99; ????????public?class?Inner{ ????????????int?b=2; ????????????public?void?test(){ ????????????????System.out.println("weibua："+a); ????????????????System.out.println("neibub："+b); ????????????} ????} ????public?static?void?main(String[]?args)?{ ????????HelloWorld?hello=new?HelloWorld(); ????????Inner?inn?=?hello.new?Inner(); ????????inn.test(); ????} }把 Outer class去掉。編程不是多層嵌套。
