Visitor's Request - 1

Hi ! Lunik. I have seen your program and made a few changes to it.

Java Program : 

import java.io.*;
public class array_names
   public static void main()throws IOException
       BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
       System.out.print("Enter The First Alphabet : ");
       char a = in.readLine().charAt(0),c;
       String[] n = new String[10];
       for(int i=0;i<10;i++)
           System.out.print("\nEnter The Name One By One : ");
        System.out.println("\nThe Name(s) Whose First Alphabet Starts With "+a+" are : ");
        for(int j=0;j<10;j++)
            System.out.println(n[j]+" ");

See, I have removed the String " s " and found two mistakes.
1) The first mistake was with the Buffer part. Your buffer " in " was probably not initialised before the loop started, so the first cell of your array went blank, generating an IndexOutofBounds error when you went for checking.

2) Secondly, your character " c " needed to be initialised before the loop "j".

3) Extra : I have further beautified your program. Please check and comment.
