I. Overview of IO:Storing the in-memory data to the hard disk (persistent device) is called: output (write) outputsoperation. Java software goes to the computer hard drive called output.The data in the hard drive is read into memory called: input (read)operation. On your computer's hard drive, go to Java software and call input.Use Java Software as a reference.Th
