Easy coding goes as follows.
psvm + tab = completes the main method
psfs + tab = public static final String
sout + tab = System.out.println("");
lets have a variable as
String name = "Manjula";
soutv + tab = System.out.println("name = " + name);
Ctrl + n = search a class
Ctrl + d = duplicate a line where cursor is, or duplicate the selection
