JAVA题：编写一个Book类用于描述图书，要求如下：
public class Book {
private String title ;
private String author;
private int sell;
public Book(){
}
public Book(String title,String author,int sell){
this.title=title;
this.author=author;
this.sell=sell;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public int getSell() {
return sell;
}
public void setSell(int sell) {
this.sell = sell;
}
public String toString() {
return "D [title=" + title + ", author=" + author + ", sell=" + sell
+ "]";
}
}
java编写一个book
public class book {
private string title;
private int pagenum;
private string type;
public book(string title, int pagenum) {
this.type = "计算机";
this.pagenum = pagenum;
this.title = title;
}
public book(string title, int pagenum, string type) {
this.title = title;
this.pagenum = pagenum;
this.type = type;
}
void detail()
{
system.out.println(this.title+","+this.pagenum+","+this.type);
}
}
public class booktest {
public static void main(string[] args) {
book book1 = new book("高等数学",123,"数学");
book book2 = new book("java编程",32);
book1.detail();
book2.detail();
}
}
Java题求解: 设计一个表示图书的book类，它包含图书的作者、书名、书号、月销售量属性，另有两
package com.yutu.test;
public class Book {
private String author;
private String bookName;
private int bookNum;
private int total;
public Book(){}
public Book(String author, String bookName, int bookNum, int total) {
super();
this.author = author;
this.bookName = bookName;
this.bookNum = bookNum;
this.total = total;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public String getBookName() {
return bookName;
}
public void setBookName(String bookName) {
this.bookName = bookName;
}
public int getBookNum() {
return bookNum;
}
public void setBookNum(int bookNum) {
this.bookNum = bookNum;
}
public int getTotal() {
return total;
}
public void setTotal(int total) {
this.total = total;
}
/**输出信息*/
public void printBook(){
System.out.println("作者："+author+"-书名："+bookName+"-书号："+bookNum+"-销售量："+total);
}
}
package com.yutu.test;
public class TestBook {
public static void main(String[] args) {
Book book=new Book();
book.setAuthor("莫言");
book.setBookName("我不想说");
book.setBookNum(147);
book.setTotal(1234);
book.printBook();
Book book1=new Book("金庸", "倚天屠龙记", 12346, 20000);
book1.printBook();
}
}
作者：莫言-书名：我不想说-书号：147-销售量：1234
作者：金庸-书名：倚天屠龙记-书号：12346-销售量：20000
编写一个图书类Book
/**1) 图书类book的属性：
id：long型，代表图书编号。
name：String类对象，代表图书馆名称。
author：String类对象，代表图书作者。
publisher:String类对象，代表出版商。
(2)图书类book的方法：
book（long i,String n, String a, String p,):有参构造函数，形参表中的参数分别初始化图书编号.图书名称。作者和出版商。
String getName():获取图书名称作为方法的返回值。
String getAuthor():获取作者作为方法的返回值。
String getPublisher():获取出版商作为方法的返回值。
public String toString():以图书名称.作者的形式作为方法的返回值。
