我完成了整个程序，并且运行良好。但是，我在使用 StringTokenizer 时遇到了问题。我有一个名为 Worker.java 的类和一个名为 TestWorker.java 的测试类...
在测试课中，我计算并打印了总工时、总工资等。但我被困在 1 个位置，即我必须将名称、id 和小时费率存储在数组中，然后使用 StringTokenizer，我必须提示用户输入工人 ID 和小时费率。
当用户输入用户工人姓名和ID时，程序输出将向用户显示工人的小时费率......
或者换句话说……
允许用户重复输入 worker-ID 和 Hours，直到用户输入并为空字符串。读取值并在适当的对象上调用方法 addWeekly()（通过在数组中搜索以找到具有指定 ID 的对象）。如果输入了不存在的 ID，则显示相应的错误消息。
请在下面查看我的编码并根据您的需要进行修改....
