Java – stores serializable objects in a file, but does not include some data

I have an object that allows me to store buffered image in my target file In the same object, I have the bufferedimage variable, which is used to cache the image after the first load from the original data array When I create an object and store it in a file, everything works because bufferedimage is null There was a problem when I was updating the loaded object and initializing variables and I wanted to save the object after the update

Is it possible to store serializable objects in a file, excluding some variables? Or maybe I can reset my bufferedimage variable in some way when stored in a file?

Thanks in advance, Sergei

Solution

You should mark attributes that you do not want to serialize as transient:

private transient BufferedImage image;
