Divide And Conquer Algorithm Implementation

I was given an algorithm to implement and i did it in java. its some divide and conquer algorithm probably some comparison sort..heres the code i wrote...

import java.util.*;//so as to get the functions for using arrays
public class main
{
public static void main(String[] args)
{
int m[]={10,2,3,4,5,6,7,8,9,1};
int result[]=new int[200];

[Code] ....

the program compiles without errors. but while running i get the following errors:

java.lang.ArrayIndexOutOfBoundsException: 10
