Thread: Please solve my problem

Write a public method called halfCount, which is passed an int as a parameter and which performs successive (integer) divisions by 2 until 0 is reached. The method returns the number of divisions required until 0 is reached.

Example: 2 --> 2 (2/2 = 1, then 1/2 = 0, so two successive divisions by 2 get you to zero)
Example: 10 --> 4 (10/2 = 5; 5/2 = 2; 2/2 = 1; 1/2 = 0)

(Hint: use a while loop in the body, and set up the loop so that at each loop iteration, the input value is halved. Use an auxiliary variable to count the number of loop iterations. When the loop finishes, return this count.)

Note that in this example you must write a complete method, including the method header line.

Hi,

We don't do other people's homework or give complete solutions here. This forum is for people to get specific help on specific issues. If you're stuck on a particular problem in that assignment, post your code (inside code tags), describe the undesired behavior, and mention what you've tried that hasn't worked.

Best of luck!

Yea!!Sorry that! I got the general idea for this question, can I post my answer and get some advices?

--- Update ---

I don't know why my answer still not currect;

public int halfCount(int j){
while (j > 0){
j = j / 2;
numDivisions++;
}
return numDivisions;
}

When I put my code into Java, it said that: Screen Shot 2017-10-25 at 7.47.21 AM.jpg
My code should return a number of divisions.

The code you posted looks good to me. I think you have a syntax error somewhere above that while loop? If you can't find it, please post the entire project code including static void main.
