ABOUT THE AUTHORS
Shufen Kuo
Shufen Kuo relocated to San Francisco Bay Area in summer of 1988, and has been a
software engineer ever since. She has extensive hands-on experience with various
platforms, from PC DOS to numerous Unix/Linux workstations, and from PC Linux to PC
Windows.
She started writing Java programs in 2001. She has been using Abstract Windowing
Toolkit (AWT) and Swing, the GUI Components of Java Foundation Classes (JFC), to
develop GUIs for her Java projects for years. And since 2012, she has immersed herself in
JavaFX; exploring its essence inspires her to write books publicizing the strength of
JavaFX.
Before developing Java applications, she had more than 12 years experience in the
development of C/C++ applications on UNIX/Linux/Solaris running X Window system.
Shufen Kuo got her M.S. in Computer Science from Washington State University in 1987.
Currently, she is developing Java applications with rich GUIs using JavaFX, as well as
writing tutorials about coding in JavaFX, utilizing her expertise on designing and
developing object oriented graphics tools.
Her publications include:
“A Two-Step String Matching Procedure,” Pattern Recognition, 24(7), 711-716,
1991.
“An Improved Algorithm to Find the Length of the Longest Common Subsequence
of Two Strings,” ACM SIGIR Forum, Spring/Summer 1989, Volume 23, Numbers 3-
4, 89-99
