java - 运行应用程序时似乎无法输入任何整数值？它只显示结果 "grade c"

Question

某公司的薪资方案如下:

Salary range for grade A: $700 - $899

Salary range for grade B: $600 - $799

Salary range for grade C: $500 - $649

工资在$600到$649之间的人，如果功绩点低于10，则为C级，否则为B级。薪水在$700到$799之间的人，如果功绩点低于20，则为B级，否则为A级。编写一个程序，读取一个人的工资和他的功绩点，并显示他的等级。

package trydontquit1;
import java.util.*;
 
public class tryagain { 
    public int salary;  
    public int merits;

    public class employee {
        employee (int inputsalary, int inputmerits){
            salary = inputsalary;
            merits = inputmerits;
        }       

        //grade the input in regard to salary and merits point
        void grade() { 
            int c = 0, b = 0, a = 0;
            c = salary - 600;
            b = salary - 700;
            a = salary - 800;
            if (c <= 49 && merits < 10)
                System.out.println("Grade = C");
            else if (b <= 99 && merits < 20)
                System.out.println("Grade = B");
            else if (b > 99)
                System.out.println("Grade = A");
        }
    }
    //to instantiate an object and to grade employee
    public static void main(String[] args) { 
        int x=0, y=0;       
        System.out.println("Grading of employee");  
        tryagain tryagain = new tryagain();
        employee sc = tryagain.new employee(x,y);
        System.out.println("Please enter salary\n");
        Scanner i = new Scanner(System.in);
        System.out.println("Please enter merits\n");
        Scanner j = new Scanner(System.in);
        sc.grade();
    }
}

看来您没有阅读输入。您需要更改 main 方法内的代码流程。请检查以下代码:

public static void main(String[] args) {
    int x = 0, y = 0;
    System.out.println("Grading of employee");
    tryagain tryagain = new tryagain();
    Scanner i = new Scanner(System.in);
    System.out.println("Please enter salary\n");
    x = i.nextInt();
    System.out.println("Please enter merits\n");
    y = i.nextInt();
    employee sc = tryagain.new employee(x, y);
    sc.grade();
}
