The use of Generic parameter raises error

public static<T> int getUsedSlotsSize(T[] arr) 
{
    int index = 0;
    while(arr[index] != null)
        index++;
    return index + 1;
}

int a = getUsedSlotsSize(arr);

eclipse tells me to change the method parameter arr to byte[]

What am I doing wrong?

Your code does not show which type is used for arr within getUsedSlotsSize(arr). If you are using

byte[] arr = new byte(anySize);
int a = getUsedSlotsSize(arr);

then you have to change the type of your array into Byte[] as mentioned in the comments.

Byte[] arr = new Byte(anySize);
int a = getUsedSlotsSize(arr);
