How to get the number of buttons within a div using webdriver?

Question

I have trying to get the number of buttons(count) enabled in a web page using their class names. But I couldn't get it as I wanted. Always I get count as 0.

    int count = 0;
    try {
        List<WebElement> Elements = driver.findElements(By.className(Locators.Buttons));
        for (int Counter = 0; Counter < Elements.size(); Counter++) {
            count = Counter;
        }
        System.out.print("############################################# " + count);

    }
    catch (Exception e)
    {

    }
    return count;

I have declared xpath as follows

//button[class='btn btn--05 thm--01']       

Other buttons have a class names starting like this. I tried using contains keyword. But didn't work.

Number of buttons enabled can be varied. Therefore buttons should be identified using above class name. How can I do it?
I have tried doing these examples too.

Answer 1

@ is missing from the Xpath you have provided:

It should be like

//button[@class='btn btn--05 thm--01'] 

This will work.

Answer 2

I tried found the solution. There was a little mistake I had done also did a little change in the xpath.
First change the By.className to By.xpath
Then changed the xpath as "//button[contains(@class, 'btn btn--05 thm--01')]"
