ArrayBinarySearch In Java

#1

I can’t find why the code is not working. The output is as if there is an infinite loop. But I can’t find what is wrong. https://ide.codingblocks.com/s/133683

public class main {

	public static void main(String[] args) {
		int numbers[] = {5,7,10,12,15,20,27,31,36,42,55,58,60,65,70,80};
      int index = binarysearch(numbers,55);
      if (index == -1) {System.out.println("The array does not include this number");}
      else {System.out.println("This number is present at index number " + index);}
	}
public static int binarysearch(int[] numbers, int search) {
	int lo=0;
	int hi=numbers.length-1;
	
	while(lo<=hi) {
        int mid = (lo + hi)/2;//Calculate mid inside while loop

		if(numbers[mid]<search) {lo = mid +1; }
		else if(numbers[mid]>search) {hi = mid -1;}
		else {return mid;}
	}
	return -1;
}
}
