Quircky while loop

[rmijares]

I am sure you guys have seen this before. I am working on the famous Employee Payroll program for a class assignment. In any case, the while loop at the end of the Employee class just keeps looping; even after I put in code asking for the employee name again. it just ignores the
String nameOfTheEmployee=input.nextLine(); and starts the loop over again. What am I doing wrong? below is the code. You will note that the code has slowly evolved from previous versions, I hope you guys can understand.

import java.util.Scanner;

public class Employee
{
//Initialize variables.
private String employeeName;
private Double employeeHours;
private Double employeeRate;
private Double weeklyPay;

//Constructor
public Employee(String name)
{
employeeName=name;
}

//Employee attributes.

//Employee name methods.
public void setEmployeeName(String name)
{
employeeName=name;
}

public String getEmployeeName()
{
return employeeName;
}

public void displayEmployeeName()
{
System.out.printf("The name of the current employee is %s.\n",getEmployeeName());
}

//Employee hours methods.

public void setEmployeeHours(Double hours)
{
employeeHours=hours;
}

public Double getEmployeeHours()
{
return employeeHours;
}

public void displayEmployeeHours()
{
System.out.printf("The number of hours worked by %s are %.2f.\n", getEmployeeName(), getEmployeeHours());
}

//Employee pay rate methods.

public void setEmployeeRate(Double rate)
{
employeeRate=rate;
}

public Double getEmployeeRate()
{
return employeeRate;
}

public void displayEmployeeRate()
{
System.out.printf("The pay rate for employee %s is $%.2f.\n", getEmployeeName(), getEmployeeRate());
}

//Employee weekly pay methods

public void calculateWeeklyPay()
{
weeklyPay=employeeHours*employeeRate;
}

public void setWeeklyPay(Double pay)
{
weeklyPay=pay;
}

public Double getWeeklyPay()
{
return weeklyPay;
}

public void displayWeeklyPay()
{
System.out.printf("The amount owed to %s for this week is $%.2f.\n", getEmployeeName(), getWeeklyPay());
}

public void calculateMultipleEmployees()
{
Scanner input=new Scanner(System.in);

System.out.print("Please enter the name of the employee and hit enter.");
String nameOfEmployee=input.nextLine();
setEmployeeName(nameOfEmployee);
System.out.println();

while (employeeName!="stop")
{
System.out.print("Please enter the employee's hourly rate:");
Double employeeRate=input.nextDouble();
setEmployeeRate(employeeRate);
System.out.println();

System.out.print("Please enter the number of hours for this week:");
Double employeeHours=input.nextDouble();
setEmployeeHours(employeeHours);
System.out.println();

displayEmployeeName();
displayEmployeeRate();
displayEmployeeHours();
calculateWeeklyPay();
displayWeeklyPay();

System.out.println("Please enter the name of the next employee.");
System.out.println("Or enter \"stop\" and hit enter to quit program:");
String nameOfTheEmployee=input.nextLine();//This line seems to be ignored by the program.
setEmployeeName(nameOfTheEmployee);//I think this one is running because the name changes.
}
}
}//end of Employee class


import java.util.Scanner;

public class EmployeeTest
{
public static void main(String args[])
{
Scanner input=new Scanner(System.in);

System.out.println();
System.out.println("Welcome to the Employee Payroll Program.");

Employee newEmployee=new Employee("unassigned");
newEmployee.displayEmployeeName();
System.out.println();

newEmployee.calculateMultipleEmployees();

//System.out.print("Please enter the name of the employee:");

Thank you for the response. However, one more question. Is the equals method part of another class? So I have to call it like I would the Scanner? I know these are very simple questions, but I have only been studying Java for two weeks.

Thank you for the response. However, one more question. Is the equals method part of another class? So I have to call it like I would the Scanner? I know these are very simple questions, but I have only been studying Java for two weeks.

The equals method is part of every class. The Object class in the java.lang package has an equals method and every class extends from the Object class implicitly, so every class has a .equals method.

You call it on objects e.g if you have string variable called myString, to test if myString has the same value as the string "test", then you do

 if(myString.equals("test")) { 
//....
}
