create ico file from base64 string in Java

Question

I get this ico base64 representation string (example, cut in the middle):

"data:image/x-icon;base64,AAABAAkAAAAAAAEAIADXwgAAlgAAAI...AAA=".

How do i create ico file from it in Java?

Edit: it didn't work with Files.write

Answer 1

In previous projects, I did the following:

byte[] data = Base64.decodeBase64(base64string);
try {
    OutputStream stream = new FileOutputStream(output_file_name)
    stream.write(data); 
} catch (Exception e) {
    //Catch IOException errors
}

Hope it helps!
