HELP!! WHAT'S WRONG WITH MY PROGRAM?

Question

It prints out "Please input next string" twice the first time and I can't figure out why. Here's the code:
import java.util.*;
public class VowelCounter {
     public static void main(String[] args) {
          Scanner read = new Scanner(System.in);
          int elements=0;
          // create string array
          System.out.print("How many strings do you want?");
          try{
               elements = read.nextInt();
          catch (InputMismatchException ime){
               System.err.println("Invalid data type!");
               System.exit(0);
          String[] testArray = new String[elements];
          // populate String array
          for (int i=0;i<testArray.length;i++){
               System.out.println("Please input next string:\n"+i);
               testArray=read.nextLine();
          } // end for
          // test array and print out result
          System.out.println(mostVowels(testArray)+ " has the most vowels.");
     } // end method main
     public static String mostVowels(String[] test){
          // create array to store count
          int[] numVowels = new int[test.length];
          // check all strings in array
          for (int i=0;i<test.length;i++){
               test[i].toLowerCase();
               // check each char in string
               for (int j=0; j<test[i].length();j++){
                    switch (test[i].charAt(j)){
                    case 'a': case 'e':case 'i':case 'o':case 'u':
                         numVowels[i]++;
                         break;
                    } // end switch
               } // end for
          } // end for
          // find string with most vowels
          int most=0;
          for(int i=0;i<numVowels.length-1;i++){
               if (numVowels[i]<numVowels[i+1]){
                    most = i+1;
          }// end for
          return test[most];
} // end class VowelCounter
Thanks a lot!

Hi,
U can do this with BufferedReader.
here is ur code
//It prints out "Please input next string" twice the first time and I can't figure out why. Here's the code:
import java.util.*;
import java.io.*;
public class VowelCounter {
     public static void main(String[] args) {
          BufferedReader bf= new BufferedReader(new InputStreamReader(System.in));
          Scanner read = new Scanner(System.in);
          int elements=0;
          // create string array
          System.out.print("How many strings do you want?");
          try{
               //elements = read.nextInt();
               elements = Integer.parseInt(bf.readLine());
          catch (Exception ime){
               System.err.println("Invalid data type!");
               System.exit(0);
          String[] testArray = new String[elements];
          int xyz =0;
          // populate String array
          for (int i=0;i<elements;i++){
               System.out.println(i+". Please input next string:\n");
               try {
                    testArray=bf.readLine();
               }catch(Exception ek){}
          } // end for
          // test array and print out result
          System.out.println(mostVowels(testArray)+ " has the most vowels.");
     } // end method main
     public static String mostVowels(String[] test){
          // create array to store count
          int[] numVowels = new int[test.length];
          // check all strings in array
          for (int i=0;i<test.length;i++){
               test[i].toLowerCase();
               // check each char in string
               for (int j=0; j<test[i].length();j++){
                    switch (test[i].charAt(j)){
                         case 'a': case 'e':case 'i':case 'o':case 'u':
                                                                                     numVowels[i]++;
                                                                                     break;
                    } // end switch
               } // end for
          } // end for
          // find string with most vowels
          int most=0;
          for(int i=0;i<numVowels.length-1;i++){
               if (numVowels[i]<numVowels[i+1]){
                    most = i+1;
          }// end for
          return test[most];
} // end class VowelCounter
