About Java swing
Java introduced swing concept to give a response to deficiency present in java awt. The AWT defines the basic set of controls, windows, and dialog boxes that support usable, but limited graphical interface.
As AWT uses native resources they are called as heavy weight components, and swing are light weight components. Presently most of programmers prefer swing to awt.
This doesn`t mean that AWT are replaced by swing.To become a swing programmer you have to learn AWT has many of awt components are used in swings.
In this tutorial you will learn both awt and swing simultaneously.
Now, lets start with basic one. How to write a swing?

How to set thread priority in java - tutorial with examples
As an application program may have many Threads ,to run all threads at a time,Thread scheduler is run.Though in theory,higher priority threads get more CPU time than lower priority threads,but in practice CPU time may vary from one operating system to other,on how OS is implementing multitask.
As a Java programmer you need to be very careful while handling threads,as java is designed to work on different environments of OS,programmer should be see that all threads will get a chance to run.
