Error using List Java

Question

I'm receiving a "can't find symbol" error when trying to run this code. It's in regard to the List line of code. It is throwing it on the List and ArrayList. I can't figure how this is implemented wrong. The script calls a class called Employee. The List is to contain all objects created from Employee. Then should be able to print the List.

import java.util.Scanner;
class PayrollProgram
{
public static void main(String[] args)
{
 Scanner scan = new Scanner(System.in);
 List<Employee> employees = new ArrayList<>();
 while (!emp.name.equals("STOP"))
 {
 Employee emp = new Employee();
 System.out.print("Employee's Name: ");
 emp.name = scan.next();
 if(emp.name.equals("STOP"))
 {
 System.out.printf("The Application is STOPPING......");
 break;
 }
 System.out.print("Enter hourly wage: $ ");
 emp.wage = scan.nextDouble();
 while (emp.wage < 0) 
 {
 System.out.printf("Please Enter a Positive Number! \n");
 System.out.print("Enter hourly wage: $ "); 
 emp.wage = scan.nextDouble();
 }
 System.out.print("Hours Worked in Week: ");
 emp.hours = scan.nextDouble();
 while (emp.hours < 0) 
 {
 System.out.printf("Please Enter a Positive Number! \n");
 System.out.print("Hours Worked in Week: ");
 emp.hours = scan.nextDouble();
 }
 employees.add(emp);
 emp.printEmployee();
 }
 for(Employee emp : employees)
 {
 System.out.println(emp.name);
 }
}
}

Answer 1

You've imported neither java.util.List nor java.util.ArrayList. You should do that.

You also need to import your Employee class, if you've defined that in a separate package.

• AwayFromMyDesk: Thanks that fixed one problem. Now I'm recieving an error on the for loop saying the variable emp is already defined in the main method. If I take out the Employee declatation for emp, I receive errors saying "not a statement", "; excepted", ": illegal start of statement"
• clstrfsck: @AwayFromMyDesk, change this: while (!emp.name.equals("STOP")) to this: while (true).

Answer 2

YOU should import correct packages & also you should create the Object of employee before while loop

Employee emp = new Employee();
while (!emp.name.equals("STOP"))
{
System.out.print("Employee's Name: ");
emp.name = scan.next();
if(emp.name.equals("STOP"))
 {
 System.out.printf("The Application is STOPPING......");
 break;
 }
System.out.print("Enter hourly wage: $ ");
emp.wage = scan.nextDouble();
while (emp.wage < 0) 
{
 System.out.printf("Please Enter a Positive Number! \n");
 System.out.print("Enter hourly wage: $ "); 
 emp.wage = scan.nextDouble();
}
System.out.print("Hours Worked in Week: ");
emp.hours = scan.nextDouble();
while (emp.hours < 0) 
{
 System.out.printf("Please Enter a Positive Number! \n");
 System.out.print("Hours Worked in Week: ");
 emp.hours = scan.nextDouble();
}
employees.add(emp);
emp.printEmployee();
}
