java - Sorting (names) using Merge Sort

Question

having problem sorting repeated Strings,

and here's my code..

i successfully sorted the first array but in the second (with repeated strings) it seems not in orderly output, can you help me to trace whats wrong in my code..

import java.util.*;

public class NewClass {
    public static void main(String[] args) {
        String[] ClassOne = { "Kring", "Panda", "Soliel", "Darryl", "Chan", "Matang", "Jollibee.", "Inasal" };
        String[] ClassTwo = { "Minnie", "Kitty", "Madonna", "Miley", "Zoom-zoom", "Cristine", "Bubbles", "Ara", "Rose", "Maria" };
        String[] names = new String[ClassOne.length + ClassTwo.length];

        mergeSort(ClassOne);
        mergeSort(ClassTwo);

        merge(names, ClassOne, ClassTwo);

        mergeSort(names);
        //Arrays.sort(names);

        for (String ClassThree : names) {
            System.out.println(ClassThree);
        }
    }

    public static void mergeSort(String[] names) {
        if (names.length > 2) {
            String[] left = new String[names.length / 2];
            String[] right = new String[names.length - names.length / 2];

            for (int i = 0; i < left.length; i++) {
                left[i] = names[i];
            }

            for (int i = 0; i < right.length; i++) {
                right[i] = names[i + names.length / 2];
            }

            mergeSort(left);
            mergeSort(right);
            merge(names, left, right);
        }
    }

    public static void merge(String[] names, String[] left, String[] right) {
        int a = 0;
        int b = 0;
        for (int i = 0; i < names.length; i++) {
            if (b >= right.length || (a < left.length && left[a].compareToIgnoreCase(right[b]) < 0)) {
                names[i] = left[a];
                a++;
            } else {
                names[i] = right[b];
                b++;
            }
        }
    }
}

and heres the output::

Ara
Chan
Cristine
Bubbles
Jollibee.
Inasal
Kring
Madonna
Matang
Miley
Minnie
Kitty
Panda
Rose
Maria
Soliel
Darryl
