I tried the printwriter and I can use it to write the information as a String. But how can I read this information to extract it as a long? I tried
in = new FileInputStream(fileLocation); in.read(readData); //readData is a byte vector String readString=new String(readData); but this does not work, because the string that I read is not the same that I store. Is there a special class that I can use, so I can read the information as a String instead of a byte vector?
