Answer / subbu
//the System class belongs to java.lang package
class System {
public static final PrintStream out;
//...
}
//the Prinstream class belongs to java.io package
class PrintStream{
public void println();
//...
}
java.lang package is default package hence no need to import
additionaly to use System class
System is having static reference of PrintStream class whihc
has println() method.
So we can directly acces the println() using out referece.
System.out.println();
