Question

This program is supposed to run through a while loop twice. The first time it runs through, it displays the name, occupation, age, salary and salary w/bonus. Yet, when the loop runs through for a second time, the name field is blank and the salary w/bonus is added onto the salary of the first employee. Thanks.

import java.util.Scanner;

public class Worker {

    public static void main(String[] args) {

        String name;
        int age;
        String occupation;
        double salary;
        double total = 10000;
        int count = 0;

        Employee employeeInfo = new Employee();

        Scanner keyboard = new Scanner(System.in);

        while (count < 2) {

            //User Name
            System.out.println("Enter your name: ");
            name = keyboard.nextLine();
            employeeInfo.setEmployeeName(name);

            keyboard.nextLine();

            //User occupation 
            System.out.println("Enter your occupation: ");
            occupation = keyboard.nextLine();
            employeeInfo.setOccupation(occupation);

            //User age
            System.out.println("Enter your age: ");
            age = keyboard.nextInt();
            employeeInfo.setAge(age);

            //User salary
            System.out.println("Enter your salary: ");
            salary = keyboard.nextDouble();
            employeeInfo.setSalary(salary);
            total = total + salary;

            System.out.println("Original Salary: " + salary);
            System.out.println("Salary with bonus: " + total);

            count++;
        }

        // employeeInfo.greetingMessage("");

    }

There is an issue with Scanner. You shouldn’t call nextLine after nextInt – I read that here. You need to make a second scanner and use it to capture the numbers, like so:

Scanner keyboard = new Scanner(System.in);
Scanner key2 = new Scanner(System.in);

When you want a string use the first one and for a number use the second:

name = keyboard.nextLine();
age = key2.nextInt();

Also, instantiate your Employee object inside the while loop or it will be overwritten with each iteration.

while (count < 2) {
  employeeInfo = new Employee();

Finally, remove the 2nd nextLine after you get the name but before you get the occupation.
