Write a class Employee. An employee has a private first name (string), private last name (string), private job title (string), private employment ID (string), private monthly income (double), private joining date (string), and private mailing address (string). Provide a default constructor, a parameterized constructor, and a clone constructor. Write separate setters and getters for each private instance variable. Your Employee class should also keep track of number of employees that have been added to your system.

Write another class BusinessConcern, which acts as your main class. Inside main method, create a one-dimensional array of objects of Employee type. At the start of your program, it should prompt for total number of employee records to be added to the system. After creating an array of desired number of employees, your program shall provide a console-based menu to user with following options:
1) New Employee Record (input: values for initialization of instance variables of new employee object/instance)
2) Change Job Title (required input: employment ID, new job title)
3) Change Monthly Income (required input: employment ID, new monthly income)
4) Change Mailing Address (required input: employment ID, new mailing address)
5) Employee Details (required input: employment ID)
6) List All Available Records
7) Exit Program
I have been working on this project for quit some hours .... But it seems to be not working ... here is the class Employee

Like I mentioned in this link:
http://www.daniweb.com/forums/thread232042.html

The JobTitle method shouldn't be in the Employee class but in the main method

Follow the instructions at the link.
Also at the options where the user enters employee number, loop through the array until you find the employee and call that employee's methods. You don't loop the array and call everybody's method, only the employee[i] that has the employee number that you entered

  1. if(empID.equals(acc[i].getjobTitle())) {
  2.  
  3. }
empId is the employee id, so Why do you compare it with the job title:
empID.equals(acc[i].getjobTitle()) Compare it with the empId of the employee in the array. Then set the job title
