Java – use the base64 class in JDK7

I tried to use the base64 class in JDK7, but the base64 I got could not resolve the error Why does eclipse throw this error?

I am using the following code

byte[] imageData = Base64.getDecoder().decode(readFile(imagePart.getInputStream()));

Even the import statement displays the same error: import Java util. Base64;

Is this class not available in JDK7?

Solution

From documentation:

So no, it is not available in JDK 7
