My program has a JScrollPane, it contains a JTextArea. The program will read in text and print it onto the JTextArea. But as the text getting large and longer, the scrollbar moves up-words. I have to use the mause to droll the scrollbar to the bottom so I can see the whole text. How can I set the scrollbar always on the bottom of the textarea as text is printed?

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
