Your code is a mess. What are you trying to accomplish? Also you posted code with no code tags, without specifying your problem and where you get it. Simply by saying it doesn't work won't get you any help

You can have a Vector of JCheckBoxes. Write a for loop that generates them from the Vector team. Or an array of JCheckBoxes

Since the range of the random numbers are between 1 and 10, you can create a String array with those numbers: [CODE] String [] numbers = {"one", "two", ...}; [/CODE] Then after you get the random number use it as index at the array. You must not forget that the …

1/(noOfPhases + 1) = 1/(3+1) = 1/4 = 0 (int) (int)/(int + int) = int/int = int 1.0/4 = 0.25 double/int = double Get it? 1/4 = 0 1.0/4 = 0.25 So I would suggest something like this: [CODE] double s = 1.0/(noOfPhases + 1); [/CODE]

<servlet-class>: You will put the name of the class. More specifically the name of the Servlet <url-pattern>: The url that maps to the servlet. Example: If you have link that points to that url, the code inside the servlet will be invoked. You can put that url anywhere you could …

How do you get the responses? Are they String objects like the one in your example or are they HttpServletRequest, HttpServletResponse objects? What you said about the JSP is irrelevant. You don't need a JSP to get the response. If they were, how you think you get the request from …

I would suggest to continue with the application and implement whatever validation you require as you progress.

[QUOTE=oneat;963278]Integer.toString ??

[CODE] <a href="ProductController?linkValue=A" target="right">A</a> [/CODE] And at the servlet use the "request.getParameter"

First of all you need to tell us what is your problem. Second, you forgot to post the ReverseString.reverseIt() method. We don't need to know how you call your method. The code you posted is correct. You call the method and you print it. What you should have posted is …

[QUOTE=VernonDozier;945712]Well, what exactly are you sorting? What's the input and what is the output supposed to be? Is it splitting a sentence into words, then sorting the words? If so, "All Big Cats" is already sorted and "Cats All Big" would turn into "All Big Cats". What's the goal here?[/QUOTE] …

You can put an id attribute at the label tag and access it using: document.getElementById

I would suggest to use the split method: [CODE] String [] sentenceArray = enteredText.split(" "); [/CODE]

If your array is an array of Strings the you can use the compareTo method: [URL="http://java.sun.com/javase/6/docs/api/java/lang/String.html#compareTo(java.lang.String)"]http://java.sun.com/javase/6/docs/api/java/lang/String.html#compareTo(java.lang.String)[/URL] [CODE] String s1 = "a"; String s2 = "b"; int i = s1.compareTo(s2); [/CODE] This method's return values represents which String is greater or lower than the other. So you can use that method …

It is because you don't pass "realName" from update.jsp to next.jsp in the request. Maybe you can put them as hidden fields at the update.jsp. (I don't really use javabeans) [CODE] <form name="formName" action="next.jsp"> <input type="hidden" name="realName" value="the value from the bean" /> <input type="hidden" name="userName" value"the value from the …

There is no reason to do it for jsp. What are you trying to accomplish?

You have to be more specific. Provide code, explain how it behaves, at which cases and how would you like to behave

First of all we need to see the code at the servlet. Second, you can have a hidden parameter in the jsp and the user clicks update to change its value: [CODE] <html><head> <script language="JavaScript"> function update() { var r=confirm("Are you sure?"); if (r==true) { document.form1.action.value='update'; document.forms[0].submit(); } else { …

Put the code in the main methods inside separate methods and classes and learn jsp

What you want, cannot be done. The easiest way is to turn your application into an applet since you will not make much change to the code that renders the GUI

[CODE] Scanner inFile = new Scanner (new FileReader("grades.txt")); PrintWriter outFile = new PrintWriter ("output.txt"); [/CODE] You need to set the exact path of your files. Not just their names, but where they are in the disk. Where have you saved your files?

What is the total? Are you saying that, you will have for example a loop running 50 times. Sometimes the loop will print, some times it will not: [CODE] for (int i=0;i<50;i++) { if (something) System.out.println("detected"); //5% of the times, this will be printed else System.out.println(""); //nothing printed } [/CODE] …

And why do you need properties file for this. Why don't you try javascript?

Your class needs to extend the JFrame class

First of all I don't get that problem. What type of computer are you using? (RAM, processor ?) Also I used to have JCreator, if you want to try it. Another IDE is the oracle's JDeveloper but personally, I don't like it very much
