IndexOutOfBound

Hi all,

I'm getting the mentioned exception while trying to merge two int arrays.

Here's the code..

Code :

---

 
public static int[] MergeArrays(int[] ArrayA, int[] ArrayB)
  {
      int ArrayAindex = ArrayA.length;
      int[] MergedArray = new int[ArrayA.length + ArrayB.length];
      int MergedIndex = MergedArray.length;
 
      for (int x = 0; x < ArrayAindex; x++)
      {
          MergedArray[x] = ArrayA[x];
      }
 
      int y;
      int z;
 
      for (y = ArrayAindex; y < MergedIndex; ArrayAindex++)
         for (z = 0; z < ArrayB.length; z++)
         {
            MergedArray[ArrayAindex] = ArrayB[z];
 
         }
 
      for (int m = 0; m < MergedArray.length; m++)
      {
          System.out.print("MergedValues: " +  MergedArray[m]);
          System.out.println("");
          System.out.print(MergedArray[m]);
      }
      return MergedArray;
  }

Just cant seem to find out whats wrong...

You're algorithm is putting all the values of ArrayB into every spot in MergedArray... Use a counter that is updated in the main loop.

Code :

---

// merging the second half of the array
int counter = ArrayA.length;
for (int i = 0; i < ArrayB.length; i++)
{
     MergedArray[counter] = ArrayB[i];
     counter++;
}

And now why didn't I think of that.. haha :)

Thanks bro.

It works fine when dealing with integers < 10;
But I get java.lang.ArrayIndexOutOfBoundsException when the integers get huge;
