我已经编写了一个 Worker 类和 Worker 的驱动程序类。我的工作类正在编译并显示所需的输出。但是在数组和 StringTokenizer 中我面临着主要问题……在TestWorker.java的第32行有一个错误,我不知道它为什么会给出问题是......
(i) 声明一个数组,该数组可以存储使用数据(名称、workerID 和 hourlyRate)构造的最多 5 个Worker对象的引用。
(ii)现在允许用户重复输入workerID和小时,直到用户输入一个空字符串。读取这些值并在适当的对象上调用方法addWeekly()(通过搜索数组来定位具有指定 ID 的对象)。如果输入了不存在的 ID,则显示相应的错误消息。
(iii)计算并显示所有工人的工资
请看我下面的代码......
//工人.java
public class Worker {
public final double bonus=100;
protected String name, workerID;
protected double hourlyRate, totalHoursWorked,tax,grossSalary,netSalary;
public Worker(){
}

this.name = name;
this.workerID = workerID;
this.hourlyRate = hourlyRate;
}
public void addWeekly(double hoursWorked){
this.totalHoursWorked = this.totalHoursWorked + hoursWorked;
}
public double gross(){
grossSalary = (totalHoursWorked*hourlyRate);
if(totalHoursWorked>=150){
grossSalary = grossSalary +100;
}
return grossSalary;
}
public double netAndTax(){
netSalary = grossSalary;
if(grossSalary>500){
tax = (grossSalary - 500) *0.3;
netSalary = (grossSalary - tax);
}
return netSalary;
}
public String getName(){
return this.name;
}
public String getWorkerID(){
return this.workerID;

"\nGross pay" + getGrossSalary() + "\nTax: " + netAndTax() +
