Question

Describe the necessary Java commands to create a Java program for creating a lottery program using arrays and methods.

Answer 1

I think each lottery ticket will cost £5 each so you would count in 5s till you reach the amount of tickets to get the answer which is £25

Answer 2

Answer: would use the for loop in this java program. A for loop is a repetition control structure that allows you to write a loop that needs to be executed a specific number of times which is why it's beneficial for the lottery program. A for loop is useful when you know how many times a task is to be repeated. import java.util.Random;import java.util.Scanner;public class LotteryGame

{  public static void main(String[] args) {     // TODO Auto-generated method stub     

Random r = new Random();     
int random[] = new int[5];   

  for (int i = 0; i < 5; ++i) {   
     random[i] = r.nextInt(48) + 1;     } 

    Scanner

sc = new Scanner(System.in);    
 int usernumbers[] = new int[5];     

System.out.print("Enter 5 numbers: ");  

   for (int i = 0; i < 5; ++i) { 

  usernumbers[i] = sc.nextInt();     }     

System.out.print("\nRandom Numbers: ");    
 for (int i = 0; i < 5; ++i)        

System.out.print(random[i] + " ");  
   System.out.print("\nUser Entered Numbers: ");     for (int i = 0; i < 5; ++i)        

System.out.print(usernumbers[i] + " ");   

  int match = 0;    
 for (int i = 0; i < 5; ++i) {       
 for (int j = 0; j < 5; ++j) {          

 if (random[i] == usernumbers[j])              
++match;        }

     }     
System.out.println("\nThere are " + match + " number of matches");  }
