“…It has integrated a true visual debugger, and it provides dynamic state visualization rather than animation of specific algorithms [Brown and Sedgewick 1985]. jGRASP provides intuitive graphical representations of program design and runtime structure, but it does not provide a visual operational semantics for Java; the visualizations are intentionally abstract in order to be understood at a high level.…”

A novel approach to the runtime visualization and analysis of object-oriented programs is presented and illustrated through a prototype system called JIVE: J ava I nteractive V isualization E nvironment. The main contributions of JIVE are: multiple concurrent representations of program state and execution history; support for forward and reverse execution; and graphical queries over program execution. This model facilitates program understanding and interactive debugging. Our visualization of runtime states clarifies the important point that objects are environments of execution. The history of object interaction is displayed via sequence diagrams, and in this way we help close the loop between design-time and run-time representations. Interactive execution is made possible by maintaining a runtime history database, which may be queried for information on variable behavior, method executions, and object interactions. We illustrate the capabilities of this system through examples. JIVE is implemented using the Java Platform Debugger Architecture and supports the Java language and libraries, including multithreaded and GUI applications.

A framework for producing dynamic data structure visualizations within the context of a lightweight IDE is described. Multiple synchronized visualizations of a data structure can be created with minimal coding through the use of an external viewer model. The framework supplies a customizable viewer template as well as high-level APIs to a graph drawing library and the Java Debugger Interface. Initial classroom use has demonstrated the framework's ease of use as well as its potential to as an aid to student learning.

“…Neither of the scenarios mentioned in the previous paragraph-for program animation or a graphical program library-is particularly novel; indeed, proponents of algorithm animation [2,3] have long advocated (and designed) just such systems. The crucial point here, however, is that craft-object language environments provide an ideal small-scale venue in which to embed these ideas into working end-user-programming environments.…”
