Name
loadStrings()
Description
Reads the contents of a file and creates a String array of its individual
lines. If the name of the file is used as the parameter, as in the above
example, the file must be loaded in the sketch's "data" directory/folder.
Alternatively, the file maybe be loaded from anywhere on the local computer
using an absolute path (something that starts with / on Unix and Linux, or
a drive letter on Windows), or the filename parameter can be a URL for a
file found on a network.
If the file is not available or an error occurs, null will be
returned and an error message will be printed to the console. The error
message does not halt the program, however the null value may cause a
NullPointerException if your code does not check whether the value returned
is null.
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.
Examples
String[] lines = loadStrings("list.txt"); println("there are " + lines.length + " lines"); for (int i = 0 ; i < lines.length; i++) { println(lines[i]); }String[] lines = loadStrings("http://processing.org/about/index.html"); println("there are " + lines.length + " lines"); for (int i = 0 ; i < lines.length; i++) { println(lines[i]); }
Syntax
