java - 如何计算工时、费率、工资，当我编译时，我收到操作标志错误。请让我知道如何计算它们

Question

当我编译它时，我收到错误，操作符号有问题，行代码错误:

Pay = (40 * Rate) + (( Hours - 40) * (1.5 * Rate));

下面是我使用的完整代码。

import java.io.*;

public class Staff {
    private int Hours;
    private int Rate;
    private int Pay;

    public Staff() {
        Hours = 0;
        Rate = 0;
        Pay = 0;
    }

    public void GetEmployee() {
        Console console = System.console();
        System.out.println(" Please Enter Hours");
        Hours = Integer.parseInt(console.readLine());
        System.out.println(" Please Enter Rate");
        Rate = Integer.parseInt(console.readLine());
    }

    public void ShowEmployee() {
        Console console = System.console();
        System.out.println(" Pays = " + Pay);
    }

    public void ComputePay() {
        if (Hours > 40) {
            Pay = (40 * Rate) + ((Hours - 40) * (1.5 * Rate));
        } else {
            Pay = (Hours * Rate);
        }
    }
}

Answer 1

//添加转换为'int'

Pay = (int) ((40 * Rate) + ((Hours - 40) * (1.5 * Rate)));
