In my Java application, I was able to get the Color of a JButton in terms of red, green and blue; I have stored these values in three ints.

How do I convert those RGB values into a String containing the equivalent hexadecimal representation? Such as #0033fA

    You can use

    String hex = String.format("#%02x%02x%02x", r, g, b);  
    

    Use capital X’s if you want your resulting hex-digits to be capitalized (#FFFFFF vs. #ffffff).
