//import java.io.PrintStream;

-> System is a class belongs to java.lang package

-> out is the static objct which belongs to java.io.PrintStream

-> Combining System.out, you get access to PrintSteam class object

-> On top of PritStream class object, we can invoke any methods in it

-> print() and println() belongs to PrintStream class

Note:

1. for each loop -> iterates only array content

class Sample{

void f1(){} // need object

static void f2() {} // object does not required

public static void main(String[] cities){

for(String cityName:cities){

System.out.println(cityName);

}

// String c1=cities[0];

// String c2=cities[1];

// PrintStream ps= System.out;

//ps.println("--- Welcome....");

//System.out.println("City name is "+c1);

// System.out.println("City name is "+c2);

System.out.println("Total Cities: "+cities.length);

System.out.println(" --- Done ---");
