Working with Main Thread : Simple

Main thread runs automatically when your program starts.
class MainThread
{
public static void main(String args[])
{
// Get current thread's object
Thread mainThread=Thread.currentThread();
// Get the name of the main thread
String oldName=mainThread.getName();
// Print the default name
System.out.println("My old name is "+oldName);
// Set a name to the main thread
mainThread.setName("My Main Thread");
// Print the new name
System.out.println("My new name is "+mainThread.getName());
// Start the loop
try
{
for(int i=5;i>=1;i--)
{
System.out.println(mainThread.getName()+": "+i);
Thread.sleep(1000);
}
}catch(InterruptedException e){
System.out.println("Main thread interrupted.");
}
}
}
