我不知道为什么我们的教授让我们做这种奇怪的打印,但它是为了我们的期末考试,一个小时后到期,我一直试图让它永远运行,但我什么也做不到。所以我有四个类,MyWord、Section、Page 和 Newspaper。MyWord 就是 MyWord。Section 包含 Section 和 MyWord。Page 包括 Section、Page 和 MyWord。报纸包含了所有这些。我有一个主要方法,它只打印您输入的信息。这是提供的唯一示例。我的所有代码都包含在课程中,以表明我实际上已经完成了工作并需要帮助。谢谢你。
Word[] w = new Word[3]; //example
w[0] = new Word(“hello”);
w[1] = new Word(“bob”);
w[2] = new Word(“smith”);
Section s = new Section(w, 20);
s.print();
//the above call to print should print off the following or something
//very similar to the following:
//Section 20: hello bob smith
my classes are also here
