Reading files in the memory

I am writing a code that will get image properties such as length and width in inches from a particular file. I was able to do it however my method does this by reading a physical file through InputStream.

My problem is that i have the file in the memory, but then i have to write in in file using the ImageIO.write method to fit the method that accepts InputStream as parameter. Is there a java api that reads a file that is in memory?


I just cant look, its killing me.

Have a look at the API documentation of BytaArrayInputStream. It reads from a byte[] instead of from a file.
