为什么我不输入我的号码？

Question

大家好，所以每当我运行代码时，我都要求我输入我的名字，工作小时数和小时工资。这是正确的但是当它进行计算时，程序使用默认构造函数中的值而不是我输入的值

import javax.swing.JOptionPane;
public class Payroll
{
private double rate;
private double hours;
private String name;
static double grossPay=0;
static double unionDues=0;
static double medicalCoverage=0;

static double state=0;
static double federal=0;
static double netPay=0;
static int numPeople=0;

{
    rate = 0;

Answer 1

您正在创建一个新的本地变量

double hours = Double.parseDouble(howmanyHours);

隐藏了小时的类字段，并没有在其他任何地方使用

Answer 2

您要将名称，小时数和工资分配给主方法中声明的变量，而不是属于double hours = Double.parseDouble(howmanyHours); 对象的变量。例如：

singh.hours = Double.parseDouble(howmanyHours);

这应该是：

singh

您还需要以这种方式修复要分配给.splice()的其他变量。
