Stack Trace

Introduction to exceptions/errors and how to read the descriptive messages indicating these problems. This is called Stack Trace.

Complete the STrace.java. Pay attention to the comments in the javafile within

To complete the STrace.java, you are to do the following:

Import simple text java.util.*;

Declare Scanner variable (input) and allow user to read a number

Declare two integer variables (data and slot) and assign zero (0) values to the variables iv. Declare an array variable (value) with an integer data type and assign index number of your choice

Compile and run the code. Input values in the data and array index boxes that will trigger the InputMismatchException. And do the following:

IMPORTANT, WORD DOCUMENT 3 LINE EXPLANATIONS OF WHY POINT OF ERROR OCCURED,,, ASWELL AS HOW TO TRACE THE ERROR.

Take a screen shot of your DrJava output console and paste in a Microsoft word doc.

Explain why this error has occurred and how to trace the error (3 lines max.)

Compile and run the code again. Input values in the data and array index boxes that will trigger the IndexOutOfBoundsException. And do the following:

Take a screen shot of your DrJava output console and paste in a Microsoft word doc.

Explain why this error has occurred and how to trace the error (3 lines max.)

Compile and run the code again. Input values in the data and array index boxes that will trigger the ArithmeticException. And do the following:

Take a screen shot of your DrJava output console and paste in a Microsoft word doc.

Explain why this error has occurred and how to trace the error (3 lines max.)
