Debugging Programs with AppBuilder for Java

Debugging Programs with AppBuilder for Java

• AppBuilder for Java provides a sophisticated debugger

• The debugger provides the following capabilities:

– Step over, or trace into, a method

– Set conditional breakpoints

– Examine and modify “watch” variables
