将对象存储在数组中，我的值在数组中不断变化

Question

So I have a while loop which stores all of my variables, but my problem is that whenever the program loops it changes the values of the object in the previous array. So employeeArray is filled with all objects of the same values rather than storing the previous value and creating a new one. I am reading text from a .csv file. Can somebody please explain to me how to store my Employee objects without them changing each loop? Let me know if you need any clarification I know I probably missed some information somebody trying to help me may need. Anyways my code is below, I have 3 different classes but Im just going to put the Employee and EmpQuery class on here. I believe the problem is with my variables in the Employee class. PLEASE HELP ME, it would be greatly appreciated.

public class EmpQuery extends Employee {

    public static void fillArrayObjects(Scanner s, Employee[] e){

        //VARIABLES
        String sNextLine;
        int counter = 0;
        int parsedString;

        String employeeID;
        String employeeName;
        String employeeDepartment;
        String employeeStartDate;
        int employeeEarnings;

        //DECLARE ARRAY TO HOLD EMPLOYEE OBJECTS
        Employee employeeArray[] = new Employee [50];//50 records I believe

        while(s.hasNext()){

            //SCANNER AND SEPARATE STRING VALUE IN LINE
            sNextLine = s.nextLine(); 

            String[] tempSplit = sNextLine.split(",(?=([^\"]*\"[^\"]*\")*[^\"]*$)", -1);

            //REMOVE EVERYTHING EXPCEPT NUMBERS [4]
            tempSplit[4] = tempSplit[4].replace(",","");
            tempSplit[4] = tempSplit[4].replace("$","");
            tempSplit[4] = tempSplit[4].replace("\"", "");
            tempSplit[4] = tempSplit[4].replace(".00","");
            parsedString = Integer.parseInt(tempSplit[4]);

            //STORE TEMP SPLITS IN NEW VARIABLES
            employeeID = tempSplit[0];
            employeeName = tempSplit[1];
            employeeDepartment = tempSplit[2];
            employeeStartDate = tempSplit[3];
            employeeEarnings = parsedString;

            //CALLING FROM EMPLOYEE CLASS
            Employee.enterData(employeeID, employeeName, employeeDepartment, employeeStartDate, employeeEarnings);

            //STORE EACH NEW EMPLOYEE IN employeeArray
            Employee i = new Employee(employeeID, employeeName, employeeDepartment, employeeStartDate, employeeEarnings);
            employeeArray[counter] = i;

            //TESTS
            System.out.println(counter + "  " +  Employee.getEarnings(employeeArray[0]));//employee[1] keep changing every loop            

            //INCREMENT COUNTER
            counter++;

        }

        System.out.println(Employee.getEarnings(employeeArray[12]));
        System.out.println(Employee.getID(employeeArray[3]));

    }

Answer 1

The main problem is that you set the variables in Employee as static, that means they are shared in every instance of the class. They should not be static so every object has their own.
