Question

Explanation / Answer

Programm 1:
/* Java program for Lottery print */

import java.util.ArrayList; // Importing classes from Util Package
import java.util.Random;// Importing classes from Util Package
public class Loto {
        public static void main(String[] arg) {
        ArrayList<Integer> al1 = new ArrayList<Integer>(); //Initialising an Array
        for(int i11 = 1; i11 <= 49; i11++) // using for loop
                al1.add(i11);
            Random rand = new Random();
                    for(int i11 = 0; i11 < 6; i11++) {
                int x1 = al1.remove(rand.nextInt(al1.size())); //Initialise the value x1
                System.out.print(" " + x1); // printing the x1 values
            }
            System.out.println();
        }
   }
Programm 2:

}
public static void Call()
{
