出版社出书查重吗

---------------------------------------------------给你修改了三个地方：borrowBooks方法中，将Sprintln("你要借吗？"); 改为：Sprintln("你要借吗？输入1表示借，其他数字表示不借。");保证输入的时候输入的数字，否则会报出异常。borrowBooks方法中，将self[score] = all[9]; 改为：self[score] = all[i];如果是all[9]，那么就始终是最后一本书籍信息了。have方法中，你是想将所借的书籍信息都打印出来。修改的比较多，下面注释代码是原来的。 void have(Books[] self) {// for (int i = 0; i < 2; i++) {// self[i]showBookInfo();// } for (int i = 0; i < 3; i++) { if(self[i]!=null) self[i]showBookInfo(); } }****************** 附上所有代码：*************************import Scanner;public class TestBook { public static void main(String[] args) { Books all[] = new Books[10]; Books self[] = new Books[3]; all[0] = new Books("java", 1, "12345", "tom", 0f, "人民出版社"); all[1] = new Books("c", 2, "12346", "tnn", 0f, "人民出版社"); all[2] = new Books("c++", 3, "12445", "mm", 0f, "人民出版社"); all[3] = new Books("c#", 4, "12365", "tt", 0f, "人民出版社"); all[4] = new Books("j2se", 5, "13345", "tosm", 1f, "人民出版社"); all[5] = new Books("j2ee", 6, "18345", "ttm", 0f, "人民出版社"); all[6] = new Books("jsp", 7, "12335", "cc", 0f, "人民出版社"); all[7] = new Books("net", 8, "12341", "bb", 0f, "人民出版社"); all[8] = new Books("ip", 9, "12343", "aa", 0f, "人民出版社"); all[9] = new Books("tcp", 10, "22345", "jj", 0f, "人民出版社"); Readers r = new Readers("xiaoming", 101, "1", 3); searchAllBooks(all); borrowBooks(all, self); have(self); ive(all, self); }}class Readers { Scanner scan = new Scanner(Sin); String names; int nums; String classes; int grade; int score = 0; // Books self[]=new Books[3]; Readers(String n, int u, String c, int g) { names = n; nums = u; classes = c; grade = g; } void searchAllBooks(Books[] all) {// 查书 for (int i = 0; i < 10; i++) all[i]showBookInfo(); // self[score]=all[0]; } void give(Books[] all, Books[] self) {// 还书 Sprintln("请输入您要还的书的书号"); int n = xtInt(); for (int i = 0; i < 10; i++) { if (n == all[i]um) { for (int j = 0; j < 3; j++) { if (self[j] == all[i]) { self[j] = null; Sprintln("还书成功"); } } } } } void have(Books[] self) {// for (int i = 0; i < 2; i++) {// self[i]showBookInfo();// } for (int i = 0; i < 3; i++) { if(self[i]!=null) self[i]showBookInfo(); } } void giveMoney() { } void borrowBooks(Books[] all, Books[] self) { Sprintln("请输入您要查找的书名："); String n = xt(); int i; for (i = 0; i < 10; i++) { if (quals(all[i]ame)) { all[i]showBookInfo(); break; } } //Sprintln("你要借吗？"); Sprintln("你要借吗？输入1表示借，其他数字表示不借。"); int j; j = xtInt(); if (j == 1) { Sprintln("借阅成功"); //self[score] = all[9]; self[score] = all[i]; score += 1; } if (score < 4) { Sprintln("您还可以借阅" + (3 - score) + "本"); } else { Sprintln("对不起，一个人只能借3本"); } }}class Books { String name; int num; String ISBN; String writer; float price; String publisher; Books(String n, int u, String i, String w, float p, String l) { name = n; num = u; ISBN = i; writer = w; price = p; publisher = l; } void showBookInfo() { Sprintln("**************************"); Sprintln("书名：" + name); Sprintln("索书号：" + num); Sprintln("ISBN号：" + ISBN); Sprintln("价格：" + price); Sprintln("出版社：" + publisher); Sprintln("**************************"); }}----------------------------------------------------

译言上面那些说是用来做电子书的，才每人几千元。打电话去出版社问不就知道了。
