Question

Write a program that contains an array with all of your friends' first names. Enter the values in any manner and order you choose (I recommend favorites first). Now take that array and sort it alphabetically so that names that start with ‘A' c me first. Look to see if you have any duplicates and if you find any, print out their names. You may use a binary search to determine this. 2. Sample output: Input list of names: Bob, Joe, John, Jeff, Kevin, Kevin, Shweta, Neil, Anderson Ordered list of names: Anderson, Bob, Jeff. Joe, John, Kevin, Kevin, Neil, Shweta

in java please

Answer 1

import java.util.Scanner;

public class SortStringArray {

  public static void bubbleSort(String[] array) {
    for (int i = 0; i < array.length - 1; i++)
      for (int j = 0;j<array.length-i-1;j++)
        if (array[j].compareTo(array[j + 1]) > 0) {
          String temp = array[j];
          array[j] = array[j + 1];
          array[j + 1] = temp;
        }
  }

  public static void main(String args[]) {
    Scanner in = new Scanner(System.in);

    System.out.print("Input list of names: ");
    String line = in.nextLine();
    String[] words = line.split(",");
    bubbleSort(words);

    System.out.print("Ordered list of names: ");
    for(int i = 0;i<words.length-1;i++)
      System.out.print(words[i]+",");
    System.out.println(words[words.length-1]);
  }
}
