Java Code:

import java.util.*;
import java.time.*;
import java.text.*;

public class Exercise9 {

public static void main(String []args){
     // Get calendar set to current date and time
      Calendar c = Calendar.getInstance();

     // Set the calendar to monday of the current week
     c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);

        System.out.println();
     // Print dates of the current week starting on Monday
       DateFormat df = new SimpleDateFormat("EEE dd/MM/yyyy");
       System.out.println(df.format(c.getTime()));
        for (int i = 0; i <6; i++) {
         c.add(Calendar.DATE, 1);
           }
        System.out.println(df.format(c.getTime()));
		System.out.println();
     }
}
