Type in multiple names and numbers, store and display afterwards.

Question:

I want to be able to type in some names and their numbers into my java app and when they're typed in for them to be stored and displayed afterwards on screen. How is this possible? Thanks!

Answer:

By using a scanner and a parallel array.

Code:

import java.util.Scanner;
 
public class NameAndNumbers {
 
   public static void main(String[] args) {
 
      Scanner sc = new Scanner(System.in);
 
      int count = 5;
 
      String name[] = new String[count];
      int number[] = new int[count];
 
      for (int i=0; i<count;i++){
        System.out.print("Enter name: ");
        name[i] = sc.nextLine();
 
        System.out.print("Enter number: ");
        number[i] = Integer.parseInt(sc.nextLine());
      }
 
      System.out.println("Output:");
      for (int i=0; i<count;i++){
        System.out.println(name[i] + " " + number[i]);
      }
   }
}

Output:

$ java NameAndNumbers
Enter name: Tom Jones
Enter number: 11
Enter name: Tom Sawyer
Enter number: 33
Enter name: Tom Brady
Enter number: 12
Enter name: Tom Cruise
Enter number: 55
Enter name: Tom Hanks
Enter number: 100
Output:
Tom Jones 11
Tom Sawyer 33
Tom Brady 12
Tom Cruise 55
Tom Hanks 100
