Data i/o streams // binary files
I have this java assignment that I need to let the user enter data or display data from an existing file. And Iām struggling with how to display data from an existing file? Please does anybody know how I can do that? :( Iām using DataOutputStream and DataInputStream I used the appending parameter so the user can read the previous entered data but itās not working
