1.Open the ch06_ex1_Invoice project. Take a screenshot after you open NetBeans and paste it into a Word or Word processing application and save it as “LastName_Assignment1”.
2.Test the Invoice Application with an invalid total like $1000 and include the dollar sign. This should cause the application to crash with a runtime error and to display an error message in the Output window. Take a screenshot of the error message and paste it into your assignment.
3.Study the error message and note the line number in the statement in the InvoiceApp class that caused the crash. Then click on the link to that line of the code. This should open the InvoiceApp.java file in the code editor and highlight the line of code that caused the crash and take a screenshot and paste it into your Word document.
4.Figure out why the application crashed because you entered in the $1000 and describe how it can be fixed in your assignment.
