Server-client password / username check in Java -

i'm building simple client-server architecture client connects server , server asks client's username , password. usernames , passwords should kept in text file. if correct, client should allowed come in commands server.

what might best way go this, including formatting of text file items should drawn from?

thanks.

you can utilize bufferedreader or scanner read username , password file. edit file, can utilize bufferedwriter.

bufferedreader br = new bufferedreader(new filereader(new file("c:\\the\\path\\of_file.txt"))); string password = br.readline();

to edit it, can use:

bufferedwriter bw = new bufferedwriter(new filewriter(new file("c:\\file.path"))); bw.write(new_password); bw.close();

all classes available in bundle java.io
