7-1 jmu-Java-m07 员工信息录入 (15分)

7-1 jmu-Java-m07 员工信息录入 (15分)
该程序包含：

Employee类：

属性：int id,String name, int age, String position,double salary

方法：getter/setter方法，toString()方法

main方法：

输入一个数num

接下去输入num行的id,name,age,position,salary，数据中间以空格进行区分

对num行的数据进行处理，生成员工列表。使用try/catch对该过程进行异常捕获处理。
如果每行数据输入的个数与所要求的不一致（如，本例中要求员工信息录行需有5个数据，然而有一行只有4个），则抛出异常提示行号以及提示信息”input error”;如果输入的数据类型不匹配，则输出行号并输出相应错误提示信息; 如果id重复，则输出错误行号并提示信息”id repeat”。

最后输出员工列表信息

输入格式:
第一行输入一个整数num

第2~num行输入id name age position salary,数据中间以空格进行分开

输出格式:
输出员工信息列表，如果有异常则先处理异常并输出提示信息

输入样例:
5
1 Andy 20 PM 3000.67
1 Rich 22 CEO 4000
2 Olive 30 CIO 6000.89
3 Jack 34 CFO salary
five fake PM

输出样例:
line:2 java.lang.Exception: id repeat
line:4 java.lang.NumberFormatException: For input string: “salary”
line:5 java.lang.Exception: input error
Employee [id=1, name=Andy, age=20, position=PM, salary=3000.67]
Employee [id=2, name=Olive, age=30, position=CIO, salary=6000.89]
