【问题描述】：

大家好，所以每当我运行代码时，我都会要求我输入我的姓名、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;

请发布您的代码。

请立即在文本编辑器中发布您的代码。

请仅在此处粘贴您的代码，而不是将其发布到谷歌驱动器/

【参考方案1】：

你正在创建一个新的局部变量

double hours = Double.parseDouble(howmanyHours);

它隐藏了小时的类字段，并且没有在其他任何地方使用

【参考方案2】：

您将名称、小时数和工资分配给在您的 main 方法中声明的变量，而不是属于您的 Payroll 对象的变量。例如：

double hours = Double.parseDouble(howmanyHours);

这应该是：

singh.hours = Double.parseDouble(howmanyHours);

您还需要以这种方式修复其他要分配给 singh 的变量。
