有没有big lao帮我把这个c语言变成java的，最后要在ecplise上实现，必有大谢

我想要达到的结果

把他变成java的

Answer 1

参考：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class 保存图书信息 {

    public static void main(String[] args) {

        Books b1 = new Books("JAVA",99);
        Books b2 = new Books("JSP",78);
        Books b3 = new Books("C++",82);
        Books b4 = new Books("MYSQL",68);
        Books arr[] = {b1,b2,b3,b4};
        
        保存图书信息 bookInfo = new 保存图书信息();
        bookInfo.writeToFile(arr);
        bookInfo.readObject();
    }
    
    void writeToFile(Books[] b) {
        try {
            File file = new File("books.dat");
            ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(file));
            oos.writeObject(b);
            oos.close();
            
        }catch(Exception e) {
            e.printStackTrace();
        }
    }
    void readObject() {
        try {
            File file = new File("books.dat");
            ObjectInputStream ois = new ObjectInputStream(new FileInputStream(file));
            Books[] arr = (Books[])ois.readObject();
            for(Books book :arr) {
                System.out.println(book);
            }
            ois.close();
            
        }catch(Exception e) {
            e.printStackTrace();
        }
    }

}

class Books implements Serializable{
    private String bookName;
    private float price;
    public Books() {}
    public Books(String bookName,float price) {
        this.bookName = bookName;
        this.price = price;
    }
    
    public String getBookName() {
        return bookName;
    }
    public void setBookName(String bookName) {
        this.bookName = bookName;
    }
    public float getPrice() {
        return price;
    }
    public void setPrice(float price) {
        this.price = price;
    }
    @Override
    public String toString() {
        return "书名："+bookName+",价格:" + price;
    }
}
