问题： -

假设一家纺织公司“Grace Textile”人力资源（HR）部门。共有80个 3个不同分支的员工。员工分为3类：被拘禁者，合同和永久性雇员。被拘禁者实习6个月，固定工资，即2万。工资是按等级计算。合同和永久雇员都有不同的薪级表。永久员工还享受养老金和小费的优惠。合同员工每月获得一次薪水和年度额外奖金。您需要编写一个Java程序，包括： •三类员工，合同员工，永久员工 •员工类将具有“员工ID”，CNIC，姓名，成绩，薪资和基本属性类别（Internee，合同和永久）。使用“I”代表internee，“C”代表“合同”和 “P”表示永久性 •CNIC的格式为123-456-789 •Contract Employee类将具有Employee类的属性/数据成员和其他会员“Bonus” •永久Employee类将具有Employee类的属性以及另外2个属性属性“小费”和“养老金” •为所有数据成员使用适当的数据类型 •写出基类和派生类的显示消息，这些消息将打印相应的Emp Id 类 •为合同员工类编写一个计算奖金的功能。卷数将存储在一个数组中。滚动号码将是您自己的vu id仅数字（8个数字，不包括前2个字符）。例如，如果您的卷号为BC12345678，则12345678将存储在数组中。加所有8位数字并将其命名为“sum”。用公式计算奖金：（sum * 1000）/ 2;打印价值奖金。

Answer 1

你的问题似乎就是这个部分：

   void calculatepay() {
       pension = ;
   }

（正如编译器告诉你的那样）
