How to use strings to read and write data?

This tutorial picks up where the Strings and Drawing Text tutorial leaves off and examines how to use String objects as the basis for reading and writing data. We’ll start by learning more sophisticated methods for manipulating Strings, searching in them, chopping them up, and joining them together.

How does processing read a text file into an array?

Once the text file is in place, Processing’s loadStrings () function is used to read the content of the file into a String array. The individual lines of text in the file each become an individual element in the array. // This code will print all the lines from the source text file.

How is a string joined together in processing?

In Strings and Drawing Text, we saw how strings can be joined together (referred to as “concatenation”) using the “+” operator. Let’s review with a example that uses concatenation to get user input from a keyboard. Processing has two additional functions that make joining strings (or the reverse, splitting them up) easy.

How are strings used in data visualization software?

We’ll start by learning more sophisticated methods for manipulating Strings, searching in them, chopping them up, and joining them together. Afterwards, we’ll see how these skills allow us to use input from data sources, such as text files, web pages, xml feeds, and 3rd party APIs and take a step into the world of data visualization.
