Question

Write a java code that allows the user to input any name (up to 10 only) and then sorts and alphabetizes them in an array without using predefined methods (.compareTo(), or any sorter functions) and then print out the results.

Answer 1

code

import java.util.*;
public class Main
{
   public static void main(String[] args)
   {Scanner s=new Scanner(System.in);
  //input
      String[] name = new String[10];
      for(int i=0;i<10;i++)
      name[i]=s.nextLine();
      
      int size = name.length;
      for(int i = 0; i < size - 1; i++)
      {
         for(int j = i + 1; j < name.length; j++)
         {
             //sort the words
            if(name[i].charAt(0)>name[j].charAt(0))
            {
               String temp = name[i];
               name[i] = name[j];
               name[j] = temp;
            }
         }
      }
      //result
      System.out.println("After sorting : ");
      for(int i=0;i<size;i++)
      System.out.print(name[i]+",");
   }
}
