Question

我在一个程序包中有三个类（LogIn，EstimatedSalary和Table）。 Table类包含一个GUI表，我想将其连接到LogIn或EstimatedSalary类中。是否比将GUI表放入我拥有的类之一更好？我尝试使用：

```
Table = null;

Table table=new table;
```
```
Table table = new Table();
```
在LogIn类中为GUI表创建内部类

虽然并非一切都正常。我的计划是在用户成功访问工作时间后显示一个弹出表。

所有类都在工作，LogIn和Estimated Salary类已经连接。我的表格信息是这样的：

      // Data to be displayed in the JTable 
    String[][] data = { 
        { "Proj 1", "5", "CSE" }, 
        { "Proj 2", "4", "IT" } 
    }; 

    // Column Names 
    String[] columnNames = { "Project Name", "Duration", "Department" }; 








public class LogIn extends EstimatedSalary {

  public static void main(String[] args) {


    int logginAttempts = 0;

    String[] accessName = {"Lea", "Lino", "Lisa"}; 
    String[] accessPassword = {"Smith", "Gray", "Collins"};


    while (true) {

        String userName = getUserNames();
        String userPassword = getPassword();
        boolean nameFound= checkUserInput(userName, accessName, userPassword, accessPassword);



        if (nameFound) {
            System.out.println("\n"+"Access Granted! Check your salary this month!"+"\n"); 
            getPositionForMember();

             **[//My first option to access the gui table here]**

            System.exit(0);
                } 


                else {



                    switch(logginAttempts) {

                        case 0: if(!nameFound){ System.out.println( "\n"+ "Please try again"  +  "\n");}
                                 else{System.exit(0);}
                                 break;

                        case 1: if(!nameFound){System.out.println("\n"+"Wrong password or Username. Please try again" +  "\n");}
                                 else{System.exit(0);}
                                 break;

                        case 2: if(!nameFound){System.out.println("\n"+ "BLOCKED.");}
                                 else{System.exit(0);}
                                 break;
                    }
                        logginAttempts++;


                    if (logginAttempts >= 3) {
                        System.out.println("Maximum loggin attempts reached.  Call Admin!");
                        System.exit(0);
                    }

        }
    }

}

预估工资类别

      public static void getPositionForMember() 
{

  double position=getPosition();

  if(position==1)
    {
      getSalaryForWD();

    }

}


public static double getSalaryForWD() 
{
    Scanner input = new Scanner(System.in);
    System.out.println("Please Enter your Estimated Hours this month:");
    double hours = input.nextDouble();
    double salary= 10.50 * hours;
    System.out.println("Your estimated Salary this month: £" + salary);
     System.out.println("Please wait a moment, the project for this year is loading...");

      **[//Second option to access the gui table]**
    return salary;
}

我可以访问if语句中包含GUI表的类吗？
