问题描述

I came across this questions on one of the online Java Tests. The options were 4,5,8 and any number of times.

我只使用了一个内部类，但从未尝试过多个内部类。我想知道是否有人知道答案。

I have only used one inner class, but have never tried multiple ones. I was wondering if anyone knows the answer.

推荐答案

我自己尝试过：答案是无数次。以下是我的测试类，我没有编译错误。

I tried on my own: The answer is any number of times. The following is my test class, I had no compilation errors.

public class Test {


    public Test ()
    {

    }
    public static void main (String args[])
    {
    new Test ();
    }

    class Test2
    {
        class Test3
        {
            class Test4
            {
                class Test5{
                    class Test6{
                        class Test7{
                            class Test8{
                                class Test9
                                {

                                }
                            }
                        }
                    }
                }
            }

        }

    }
