How to make a sample Payroll Management System in Core Java and convert it into Windows Application

Here i'm going to explain a sample payroll application...

Step 1:-Create a welcome page like below

This is welcome page in my payroll application you can design it in your own style and here i included a progress bar and it will work when page is loaded and after that you will get a login page shown below

I will learn how to create this simple progress bar in NetBeans.This progress bar is also working based on the "Thread Concept".

Step 1:-In your design part place progress bar anywhere in your
form you can select it from Swing Controls Palette.Also you can set its properties.

Step 2:-Go to your source code part and create a inner class and implement it with Runnable interface.

Step 3:-Inside the class you can write the code below....


 public class Thread1 implements Runnable /* Inner Class */
    {
        int i;
        public void run()
        {
            for(i=0;i<=100;i++)
            {
                progbar.setValue(i);
                try
                {
                    Thread.sleep(20);
                }
                catch(InterruptedException ie)
                {}
            }
            Login l=new Login(); /* Object creation of next form */
            l.setVisible(true);
            tfun(i);
        }
    }

/* function inside outer class */


 public void tfun(int i)
    {
        if(i==101)
            this.hide(); /* hide current form when progress bar completed */
    }


Try this code....remaining forms will be explain in coming days...
