Java BinarySearch

Question

Can I get some help please? I have tried many methods to get this to work i got the array sorted and to print but after that my binary search function doesnt want to run and

Answer 1

Here

    if (mid > key) 
        high = mid -1;
    else if (mid < key) 
        low = mid +1;
    else 
        return mid;

You're comparing index to a value (key) in array. You should instead compare it to a[mid]

And,

System.out.println("Found " + key + " at " + binarySearch(double a[], key));

Should be

System.out.println("Found " + key + " at " + binarySearch(a, key));
