所以我有一个存储我所有变量的while循环，但我的问题是每当程序循环时它会改变前一个数组中对象的值。因此，employeeArray充满了具有相同值的所有对象，而不是存储前一个值并创建一个新值。我正在从.csv文件中读取文本。有人可以向我解释如何存储我的Employee对象而不更改每个循环吗？如果您需要任何澄清，请告诉我，我知道我可能错过了某些人试图帮助我可能需要的信息。无论如何我的代码在下面，我有3个不同的类，但我只是将Employee和EmpQuery类放在这里。我认为问题在于Employee类中的变量。请帮助我，非常感谢。
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]));
}

主要问题是您将Employee中的变量设置为静态，这意味着它们在类的每个实例中共享。
它们不应该是静态的，所以每个对象都有自己的。
