Hi I'm creating a mergesort visualization I'm getting this error . Here is the relevant code

class MergeSort{
//member Variables for the strobed version of the merge sort

int high, low, mid, a;

boolean m_bCheckingInnerloop;

MergeSort()
{
     InitStrobe();
}

void InitStrobe()
{
     high=0;
     m_bCheckingInnerloop=false;
}

//This is the original merge sort; for reference
//void merge(int,int,int);
void merge_sort(int [] inArray,int low,int high)
{
int mid;
if(low<high)
{
 mid=(low+high)/2;
 merge_sort(inArray,low,mid);
 merge_sort(inArray,mid+1,high);
 merge(inArray,low,mid,high);
}
}

void merge(int [] inArray, int low, int mid,int high)
{
int h,i,j,k;
h=low;
i=low;
j=mid+1;

while((h<=mid)&&(j<=high))
{
 if(a[h]<=a[j])
 {
  inArray[i]=a[h];
  h++;
 }
 else
 {
 inArray[i]=a[j];
  j++;
 }
 i++;
}
if(h>mid)
{
 for(k=j;k<=high;k++)
 {
  inArray[i]=a[k];
  i++;
 }
}
else
{
 for(k=h;k<=mid;k++)
 {
  inArray[i]=a[k];
  i++;
 }
}
for(k=low;k<=high;k++)
 {
  a[k]=inArray[k];
 }
}

}  


i havent created the strobed version yet, i just want to it compile without visualization
