Write a program in Java to store 20 different names and telephone numbers of your friends in two different Single Dimensional Arrays (SDA). Now arrange all the names in alphabetical order and display all the names along with their respective telephone numbers using selection sort technique.

import java.util.Scanner;

public class KboatTelephoneBook
{
    public static void main(String args[]) {
        final int SIZE = 20;
        Scanner in = new Scanner(System.in);
        String names[] = new String[SIZE];
        long telNos[] = new long[SIZE];
        System.out.println("Enter " + SIZE + " names and telephone numbers");
        for (int i = 0;  i < SIZE; i++) {
            System.out.print("Enter Name: ");
            names[i] = in.nextLine();
            System.out.print("Enter telephone number: ");
            telNos[i] = in.nextLong();
            in.nextLine();
        }
        
        //Selection Sort
        for (int i = 0; i < SIZE - 1; i++) {
            int min = i;
            for (int j = i + 1; j < SIZE; j++) {
                if (names[j].compareToIgnoreCase(names[min]) < 0) {
                    min = j;
                }
            }
            String temp = names[min];
            names[min] = names[i];
            names[i] = temp;
            
            long t = telNos[min];
            telNos[min] = telNos[i];
            telNos[i] = t;
        }
        
        System.out.println("Name\tTelephone Number");
        for (int i = 0; i < SIZE; i++) {
            System.out.println(names[i] + "\t" + telNos[i]);
        }
    }
