[英]Best way to store multiple data types to one array / table in java
I've got a small project I'm working on in which I'm trying to be able to pull data from a massive .txt file. 我有一个正在处理的小项目,试图在该项目中从庞大的.txt文件中提取数据。 The files got about 100 rows of the following:
这些文件包含以下内容的约100行:
Employee ID -- Salary -- Currently Employed == Employee Name == Paycheck Amounts
1 100 true == Michael == 300 200 100 300
2 200 true == Stephanie == 4000 2300 1000
Essentially I need to be able to call Employee ID at a later date and it shows their salary, employment etc. The other issue is that the paychecks could be either 1 paycheck or 50 从本质上讲,我需要能够在以后致电Employee ID,并显示他们的薪水,工作情况等。另一个问题是薪水可以是1薪水或50
I'm curious what are your thoughts on how to store this data? 我很好奇您对如何存储此数据有何想法? I can split the lines and what not to actually get it but what's the best method of storing it all at once.
我可以分界线,什么不是真正得到它,但是一次存储所有东西的最佳方法是什么。
Ideally what I would like to do is be able to call ID 2 and see its Stephanie and her last 3 paychecks were 4000, 2300 and 1000. 理想情况下,我想打电话给ID 2并查看其Stephanie,她最近的3张工资分别是4000、2300和1000。
This seems like a bit of a big task for my small Java skills. 对于我的小型Java技能来说,这似乎是一项艰巨的任务。 Any thoughts / assitance would be highly appreciated!!!
任何想法/协助将不胜感激!!!
This is pretty standard stuff: 这是很标准的东西:
class EmployeeRecord {
final int employeeId;
final int salary;
final boolean isCurrentlyEmployed;
final String employeeName;
final List<Integer> paycheckAmounts = new ArrayList<>();
EmployeeRecord(
int employeeId,
int salary,
boolean isCurrentlyEmployed,
String employeeName) {
this.employeeId = employeeId;
this.salary = salary;
this.isCurrentlyEmployed = isCurrentlyEmployed;
this.employeeName = employeeName;
}
}
Put these in an array 将它们放在一个数组中
List<EmployeeRecord> records = new ArrayList<>();
也许您可以使用地图来存储数据。
Map<String, YourEmployeeObject> records = new HashMap<>();
Create a Employee Class .. 创建一个员工类..
class Employee{
final int employeeId;
final int salary;
final boolean isCurrentlyEmployed;
final String employeeName;
final List<Integer> paycheckAmounts = new ArrayList<>();
Employee(
int employeeId,
int salary,
boolean isCurrentlyEmployed,
String employeeName) {
this.employeeId = employeeId;
this.salary = salary;
this.isCurrentlyEmployed = isCurrentlyEmployed;
this.employeeName = employeeName;
}
}
Then create employee object And add all employees to the list of employees 然后创建员工对象并将所有员工添加到员工列表中
List<Employee> employees= new ArrayList<>();
