Description Creates a BufferedReader object that can be used to read files line-by-line as individual String objects. This is the complement to the createWriter function.

Starting with Processing release 0134, all files loaded and saved by the Processing API use UTF-8 encoding. In previous releases, the default encoding for your platform was used, which causes problems when files are moved to other platforms.
Syntax
createReader(filename)
Parameters
filename Name of the file to be opened
Usage Application
