System:It is the class Name which is available in java.lang
package.

out: is the static variable(public static final
java.io.PrintStream out)

Analysis of out variable:
So many people are conflict about this out,
a)Either it is object or variable.

Reason:In java there is no static object(means with static
keyword it is called variable only)

println:is a method which is available in
Java.io.PrintStream class)

the step is considered by java team like this

class System
{
public static final java.io.PrintStream out=new PrintStream();
------
}
So they called System.out.println()
