Java， "Variable name"无法解析为变量

Question

我使用 Eclipse 和 Java，我得到这个错误:

"Variable name" cannot be resolved to a variable.

使用这个 Java 程序:

public class SalCal {
    private int hoursWorked;
    public SalCal(String name, int hours, double hoursRate) {
        nameEmployee = name;
        hoursWorked = hours;
        ratePrHour = hoursRate;
    }
    public void setHoursWorked() {
        hoursWorked = hours;     //ERROR HERE, hours cannot be resolved to a type
    }
    public double calculateSalary() {
        if (hoursWorked <= 40) {
            totalSalary = ratePrHour * (double) hoursWorked;
        }
        if (hoursWorked > 40) {
            salaryAfter40 = hoursWorked - 40;
            totalSalary = (ratePrHour * 40)
                + (ratePrHour * 1.5 * salaryAfter40);
        }
        return totalSalary;
    }
}

导致此错误消息的原因是什么？

Answer 1

如果您查看变量“hoursWorked”的范围，您会发现它是该类的成员(声明为 private int)

您遇到问题的两个变量作为参数传递给构造函数。

错误消息是因为“小时”超出了 setter 的范围。
