Stack Trace
The first sample execution in Fig. 11.2 shows a successful division. In the second execution, the user enters the value 0 as the denominator. Several lines of information are displayed in response to this invalid input. This information is known as a stack trace, which includes the name of the exception (java.lang.ArithmeticException) in a descriptive message that indicates the problem that occurred and the method-call stack (i.e., the call chain) at the time it occurred. The stack trace includes the path of execution that led to the exception method by method. This helps you debug the program.
