Question

我的程序应该显示工人总薪水的计算，但不管怎么说，在包括程序结束后，所有输入都没有显示任何结果。

还要检查输入的总小时数是否超过40，如果是，则计算加班工资。

 public class GajiTest {
 public static void main(String[] args)
{

    Scanner input= new Scanner(System.in);
    System.out.print("Enter number of Employees: ");
    int numberOfEmp= input.nextInt();

    int[] arrayList= new int[numberOfEmp];

    for (int i = 0; i < arrayList.length; i++){

    System.out.print("Enter Employee Name: ");
    String empName= input.next();

    System.out.print("Enter hourly rate: ");
    int rate= input.nextInt();

    System.out.print("Enter hours worked: ");  
    int hours=input.nextInt();

    class Salary {

    public double CalculateGaji(int hours,int rate){

   if (hours >=40)
   {
   double regPay=  hours * rate;
   double otPay = (hours-40) *(rate*1.5);
   double totalPay= regPay + otPay;
   System.out.print("\nEmployee name: " + empName+"\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
  }

    else
   {
   double regPay=  hours * rate;
   double otPay =0;
   double totalPay= regPay + otPay;
   System.out.print("\nEmployee name: " + empName+ "\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
  }

  }
  }
  }}}

我想问题是添加两行试试这个：

public static void main(String[] args)
{

    Scanner input= new Scanner(System.in);
    System.out.print("Enter number of Employees: ");
    int numberOfEmp= input.nextInt();

    int[] arrayList= new int[numberOfEmp];

    for (int i = 0; i < arrayList.length; i++){

    System.out.print("Enter Employee Name: ");
    String empName= input.next();

    System.out.print("Enter hourly rate: ");
    int rate= input.nextInt();

    System.out.print("Enter hours worked: ");  
    int hours=input.nextInt();

    Salary sal=new Salary();
    sal.CalculateGaji(hours,rate,empName);




    }
    }
    }



class Salary {

    public void CalculateGaji(int hours,int rate,String empName){

   if (hours >=40)
   {
   double regPay=  hours * rate;
   double otPay = (hours-40) *(rate*1.5);
   double totalPay= regPay + otPay;
   System.out.print("\nEmployee name: " + empName+"\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
  }

    else
   {
   double regPay=  hours * rate;
   double otPay =0;
   double totalPay= regPay + otPay;
   System.out.print("\nEmployee name: " + empName+ "\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
  }

 }
}

为什么不打印任何内容是因为您没有调用CalculateGaji()的方法class Salary。

您需要通过创建类Salary的对象来调用它。（在主方法中的本地类之后。）

Salary salary = new Salary();
salary.CalculateGaji(hours,rate);

除此之外，还有一些我想说的话，

您正在创建一个整数数组int[] arrayList= new int[numberOfEmp]; ArrayList是另一回事。 What is an ArrayList?不应该将变量的名称写为arrayList。在某个阶段可能会让你感到困惑。
根据您的代码，您已在class Salary中创建了课程main method。这样它就变成了[Local Class][2]。如果这是你想要的，那就找到了。否则，您可以编写class Salary外侧主要方法和课外class GajiTest。

但我认为没有必要创建任何本地类来实现它。您可以通过以下方式直接执行此操作，

public static void main(String[] args)
{

    Scanner input= new Scanner(System.in);
    System.out.print("Enter number of Employees: ");
    int numberOfEmp= input.nextInt();

    int[] arrayList= new int[numberOfEmp];

    for (int i = 0; i < arrayList.length; i++){

    System.out.print("Enter Employee Name: ");
    String empName= input.next();

    System.out.print("Enter hourly rate: ");
    int rate= input.nextInt();

    System.out.print("Enter hours worked: ");  
    int hours=input.nextInt();


   if (hours >=40)
   {
   double regPay=  hours * rate;
   double otPay = (hours-40) *(rate*1.5);
   double totalPay= regPay + otPay;
   System.out.print("\nEmployee name: " + empName+"\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
  }

    else
   {
   double regPay=  hours * rate;
   double otPay =0;
   double totalPay= regPay + otPay;
   System.out.print("\nEmployee name: " + empName+ "\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
  }

  }

从您的代码中，我认为您要做的是创建一系列员工并打印出他们的姓名和薪水。如果您愿意，代码中存在多个错误，无法使其正常运行。

以下是创建员工阵列并根据您的CalculateGaji函数打印出姓名和薪水的代码：

public class calculateSalary {

static class employee{
    private double rate;
    private double hours;
    private String empName;

    public employee(){}

    public void setRate(double value){
        rate = value;
    }

    public void setHours(double value){
        hours = value;
    }

    public void setName(String value){
        empName = value;
    }

    public void CalculateGaji(){

           if (hours >=40){
               double regPay=  hours * rate;
               double otPay = (hours-40) *(rate*1.5);
               double totalPay= regPay + otPay;
               System.out.print("\nEmployee name: " + empName +"\n Regular pay: " +   regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
          }

            else{
                double regPay=  hours * rate;
                double otPay =0;
                double totalPay= regPay + otPay;
                System.out.print("\nEmployee name: " + empName + "\n Regular pay: " + regPay +"\n Overtime pay: " + otPay+ "\n Total pay: " + totalPay+ "\n"+ "\n");
          }
    }

}

public static void main(String[] args){
        Scanner input = new Scanner(System.in);
        System.out.print("Enter number of Employees: ");
        int numberOfEmp= input.nextInt();

        employee[] employeeArray= new employee[numberOfEmp];

        for (int i = 0; i < employeeArray.length; i++){

            employeeArray[i] = new employee();
            System.out.println("Enter Employee Name: ");
            employeeArray[i].setName(input.next());

            System.out.println("Enter hourly rate: ");
            employeeArray[i].setRate(input.nextDouble());

            System.out.println("Enter hours worked: ");  
            employeeArray[i].setHours(input.nextDouble());
        }

        for(int i = 0; i < employeeArray.length; i++){
            employeeArray[i].CalculateGaji();
        }
}
}

希望这有帮助。
