检查Java中getter和setter的可用性

Question

我有一个带有私有变量bookName（类型:string)、bookPrice（类型:int)、authorName（类型：string）的类Book，我为这些私有变量包含了适当的getter和setter方法。

另一个类TestBook创建有主方法。我需要从用户获得详细信息bookName，bookPrice,authorName。

对象，并使用设置器为其属性赋值。也可以使用getters方法打印输出。

我写了整个代码，但失败了。

Fail1:检查bookName属性的getter/setter的可用性Fail2:检查bookPrice属性的getter/setter的可用性Fail3:检查authorName属性的getter/setter的可用性

book.java

 public class  Book {

         private String bookName;
         private int bookPrice;
         private String authorName;

         //getters

         public String getbookName(){
             return bookName;
         }

        public String getauthorName(){
              return authorName;
        }
        public int getbookPrice(){
            return bookPrice;
        }

       //setters


        public void setbookName(String newName){
             this.bookName = newName;
        }
        public void setbookPrice(int bokPrice){
            this.bookPrice = bokPrice;
        }
        public void setauthorName(String author){
            this.authorName = author;
        }


    }

testbook.java

 import java.util.Scanner;

     class TestBook {

         public static void main(String[] args){
         Scanner my = new Scanner(System.in);

         String name1,name2;
         int num;

        // Getting user input

        System.out.println("Enter the Book name:");
        name1 = my.nextLine();

        System.out.println("Enter the price:");
        num = my.nextInt();

        String re = my.nextLine();

        System.out.println("Enter the Author name:");
        name2 = my.nextLine();

        //Setting values of private variable using setters

        Book myObj = new Book();
        myObj.setbookName(name1);
        myObj.setbookPrice(num);
        myObj.setauthorName(name2);

        //Printing values using getters

        System.out.println("Book Details");
        System.out.println("Book Name :"+myObj.getbookName());
        System.out.println("Book Price :"+myObj.getbookPrice());
        System.out.println("Author Name :"+myObj.getauthorName());



        }
    }

Answer 1

getbookname()应为getbookname()。对于所有getter和setter来说，setbookname()应该是setbookname()等等。这是正确的Java约定。我只能假设你的测试人员正在寻找的标准。
