Improvement of Transitions and Flow Visualization TFVIS for Exception Handling

It takes much time in debugging process. To find bugs effectively, it’s important to understand the dynamic behavior of programs. To support understanding the dynamic behavior, we developed TFVIS(transitions and flow visualization). It provides visualization of data transitions and data flow of Java programs. But it visualizes only some control structures and expression. Therefore, we newly corresponded to Exception-handling. This improves the usefulness of TFVIS as a tool to support the understanding of the dynamic behavior of programs.
