Writing multiple variables to file
Hey guys, im wondering if anyone can help me with writing multiple variables to one .txt on the HDD. Ive already programmed the following:
BufferedWriter writePaid =new BufferedWriter(new FileWriter("C:\\Debt Logger\\Users\\" + user + "_log.txt"));
writePaid.write(paidAmount);
writePaid.flush();
writePaid.close();
but with that i can only write one variable value to the file... is there a way to have maybe line 1 be value of paidAmount, line 2 be value of debtAmount and then have BufferedReader read from which ever of the 2 lines i need it to? Thanks in advance for the help.
Why can you only write 1 variable to the file? Why can't you perform multiple 'write()s'?Once you read in a line, examine its content, discard it if it doesn't meet your requirements or process it if it does.Good luck.

No. You'd have to read the file line by line and just ignore the first N lines that you don't want to deal with.
Or, if a line will be a fixed length, then you could use RandomAccessFile to jump immediately to a specific byte position in the file.

Ok i just got my program to read each line! Thanks guys!
Now for getting it to write line by line...
Is there a way to do that without using PipedWriter?
so if i had these variables for example:
int bunnies = 12, birds = 18, snakes = 6, dogs = 23;
how would i get it to write to the file like this:
12
18
6
23
even if i have to write them as Strings instead of Integers thats not problem because i could just Parse them into Integers when i read them in...
