2 Summary of Previous Session Summary of Previous Session Java AWT and Swing components Drag and Drop Graphics and Multimedia Components (JavaMedia) JavaBeans Readings Class Project & Assignment #2b 3 Java Technologies/Features in Scope Technologies: Collections Framework Input Method Framework Swing Drag and Drop JavaBeans JNI Security Language Features: Threads Assertions 4

3 Part I Session 4 Epilogue 5 Drag and Drop ( See Session 4 Handout on Drag and Drop Data Transfer Adding Drag and Drop to a JTree In J2SE 1.4, JTree supports Drag but developers must implement and install a custom TransferHandler to fully support imports of data on Drop targets

4 JavaBeans and JAF ( See Session 4 Handout on Component Modeling with JavaBeans Download the BeanBuilder Experiment with the online tutorial orial.html Download JAF Experiment with the JAF demo programs 7 Part II Java Media APIs 8

9 Part IV Java Generative Programming 17 JavaCC ( JavaCC is the most popular parser generator for use with Java applications Parser generator Tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar JavaCC provides a tool called JJTree that can build a parse tree 18

12 Assignment Readings Mastering Java 2: Part 2 Chap. 10, 11 Expert One-on-One: Chapter 2-4 as applicable (cont.) Selected readings mentioned in class or referenced in the handouts Handouts posted on the course web site Assignment #2b: (submit report and implementation archive) Design and implement a version of assignment #2a, and #2b that uses Visual XBean (see Xbeans documentation at Visual XBeans are JavaBeans designed to display XML documents. They use Swing components to display XML documents as JTrees, JTables, or other Swing components. Extra credit: Use JNI to obtain your XML document from an underlying C or C++ program. Refer to the Homework #2 Specification posted on the course Web site.
