1.Write a JSP that simply displays the current date and time when it is opened. 2.Create a simple HTML page containing a single button that takes the user to a JSP called Count1.jsp. Now create a JSP with this name that uses a session variable (i.e., an attribute set up by object session) to display the number […]

Extend Count1.jsp (copying and renaming it as Count2.jsp?) so that the application object is used to display the total number of times that the page has been visited by anybody (in all sessions). If you use a name for the JSP that is different from the one used in the previous question, remember to modify the initial HTML page

1. There is now too much Java code in the JSP of the previous exercise and this should really be moved to a servlet. Introduce a servlet that will do the background processing and then redirect control to the (reduced) JSP. 2. Re-write PersonalServlet (and its associated HTML page) from Chapter 8 so that a JSP is

Create an error page for the above JSP that displays a meaningful error messageand allows the user to re-enter his/her name if no name was entered initially. Modify the original JSP so that (a) it registers the error page and (b) it throws a general Exception object if no name is entered by the user.

1.Re-write AdderServlet (and its associated HTML page) from Chapter 8 so that a JSP is used instead of the servlet. Create an error page that displays a meaningful error message if non-numeric data is entered and allows the user to re-enter the values. 2. (i) If you are using the Finances database, then you need take no action here.

Modify the calculator bean so that the user can set the background colour of the result box to red, green or blue, via method setResultBground. Then modify the code for the previous exercise by adding a button that allows the user to make use of method setResultBground (probably via method JOptionPane.showInputDialog).

19. CMA interpreters. Implement an interpreter for the C-Machine in the programming language of your choice. • Choose a suitable data type for instructions. Take into account that some instructions have arguments, but some have not. • Implement the datastructures C and S. • Test your interpreter with the factorial function and the main function:

5.22 (De Morgan’s Laws) In this chapter, we discussed the logical operators &&, || and !. DeMorgan’s laws can sometimes make it more convenient for us to express a logical expression. Theselaws state that the expression !( condition1 && condition2 ) is logically equivalent to the expression( !condition1 || !condition2 ). Also, the expression !(

Write three functions in C or C++: one that declares a large array statically, one that declares the same large array on the stack, and one that creates the same large array from the heap. Call each of the subprograms a large number of times (at least 100,000) and output the time required by each.
