I have been tinkering around with Java's FileReader, FileWriter & BufferedReader; however, this time I will use screen shots to illustrate parts of the code instead of pasting it and formatting it to fit nicely. Extremely time consuming...not like this post will be quick either! So here we go...not sure if I am going to enjoy this post.
1) We instantiate the FileWriter
2) My output file will be "numbers.dat"
3) Write numbers from 1 to 100 separated by "," commas to the "numbers.dat" file
4) Close the FileWriter
5) Instantiate the FileReader
6) Instantiate the BufferedReader
7) Pass data from Buffer to textData variable
8) For Schnitz'N'Giggles for you (Beer Fest) bloaks, let's display all even numbers from 1-100 on the screen
9) Close Buffer
10) Instantiate a second FileWriter
11) Append all odd numbers from 1-100 to "numbers.dat"
12) Close the second FileWriter
13) Instantiate a second FileReader
14) Instantiate a second BufferedReader
15) Pass Buffered data to textData variable
16) Print results to screen
End Results...JOptionPane Window prompts
Create "numbers.dat" file prompt
Display even numbers prompt
Append odd numbers to "numbers.dat" prompt
Display final results prompt
Proof file was created!
Screen output! (Even numbers highlighted)
File data content! (Appended numbers highlighted)
