Please anybody can explain the pupose of "System.out.println("....");"
We know System class comes under java.lang package.But println method belongs to PrintStream class which comes under java.io package.So,even if we donot insert java.io package how println("....") method is executed.

"out" is a field in the System class of type PrintStream. That PrintStream is in the java.io package does not matter, as it is never used directly. If "PrintStream" appeared anywhere in the source, it would need to be imported; because it does not, it needn't be.

In the System.out.println "out" is a static object of the PrinStream class which is created in the lang package(default package).It is used to call the println() in the PrintStream class which does the printing job.

A programmer need not import io package for doing simple output operations.
It is sorta covered in the JavaRanch Style Guide.
