You need to first tell us what exactly are you expecting to be passed in the "code" parameter. Give us an example of how a correct format of String inside "code" (one that would output "yes") and an incorrect format example (one that would output "no"). Also are you even …

[QUOTE]i would say lazy student wouldn't even bother posting questions. [/QUOTE] Do not be so judgmental, If you hang around here long enough you will see your fair share of them.

Put this chunk of code in a main inside class, compile it, then run it, add a System.out.println() after every statement to trace what is happening to your variables. Thats the most optimal way of finding out rather than asking people for a line by line explanation.

Tomcat by default doesn't have support for JSF (amd definitely Tomcat 5.5 doesn't), Are you sure the new place has the JSF libraries because the following suggests the JSF libraries are mssing.

Yes, Next time you post wrap your code inside [noparse][code=java] and [/code][/noparse] tags. Also what do you need help for ? Tell us the problem (compile errors,logic problems etc etc) you are facing and this time please do not give the reason "I am a beginner" for not attempting something.:)

This is more of a core java question, So it should have been posted in the Java forum. Anyways take a look at the javadocs of the [URL="http://java.sun.com/javase/6/docs/api/java/lang/String.html"]String[/URL] and [URL="http://java.sun.com/javase/6/docs/api/java/lang/StringBuffer.html"]StringBuffer[/URL] class you might find what you are looking for there, most probably it is the substring ([URL="http://java.sun.com/javase/6/docs/api/java/lang/String.html#substring(int,%20int)"]1[/URL],[URL="http://java.sun.com/javase/6/docs/api/java/lang/String.html#substring(int)"]2[/URL]) menthod..

[QUOTE]"allocated" clearly prints as equal to c[/QUOTE] But the condition in your do-while loop is [code=java] while(allocated < c) [/code] So definitely it wouldn't stop because technically "allocated" is not less than "c". If you want it to terminate when "allocated" and "c" are equal also then change the "<" …

If you are using a Swing Form to get Input then I would suggest dropping the while loop altogether because your actionPerformed() method will be called whenever your user clicks on the GuessButton and you can perform all the necessary processing then.

Well one word about the StringTokenizer class, this is what the javadocs have to say about it:- [QUOTE]StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code.

@transplantedNYr If you are just begining Java as it appears to be, just like verruckt I suggest you use a minimalistic IDE, With Eclipse just as you noticed now by asking about the compile button, you will get lost trying to figure your way around. Use a minimalistic IDE without …

Check out [URL="http://java.sun.com/docs/books/tutorial/uiswing/"]this tutoria[/URL]l on swing in case you want to get your GUI up and running and then you might want do some validations on the username and password either in the database (then you might want to look here for [URL="http://java.sun.com/docs/books/tutorial/jdbc/basics/index.html"]jdbc)[/URL] or want to use [URL="http://java.sun.com/docs/books/tutorial/essential/io/"]Files[/URL] instead.

Well to calculate days I would prefer a more simpler method like this :- [code=java] // Current day would store the index of the day in the Array // 0 points to Sunday. int currentDay = 0 String days = {"Sun", "Mon", "Tue", "Wed", "Thr", "Fri", "Sat" }; // Now …

[code=java] final char grade; [/code] Declaring a variable as "final" is almost like making it a constant and hence its value cannot be changed later (which you are doing in the "if else" blocks.

First of all you will need an API (provided by one of various currency exchange websites) which will feed you the data if you want live /real time exchange rates.

Now I am going to make some assumptions here on your merge method, My main assumption is if your method is called as [icode]arr2.merge( arr1 , arr);[/icode] then you want the contents of arr1 and arr merged and in sorted order inside arr2. Now if thats the case, why don't …

Start your own thread if you are facing any issues do not simply revive ancient relics. Next there is also a separate forum for JSP in the Web Development Section, you should have made a thread there. Also define what you mean by "NOT-WORKING" and "WORKING WELL". Check the logs …

The tomcat container (or whichever container you are using) itself creates and manages threads concerning your JSP page when it gets requests to serve your JSP. What I think you are looking for is how to track sessions in JSPs. [URL="http://www.jsptut.com/Sessions.jsp"]Here[/URL] is a basic example.

Are you using httpd or are you using Tomcat ? AFAIK httpd doesn't support JSPs it supports CGI and PHP technologies.

The following lines should be inside a method and not placed directly inside a class, you may place only member declarations / initialisations / methods or static blocks of code directly there. [code=java] Button1.addActionListener(listener); Button2.addActionListener(listener); Button3.addActionListener(listener); Button4.addActionListener(listener); Button5.addActionListener(listener); Button6.addActionListener(listener); Button7.addActionListener(listener); Button8.addActionListener(listener); Button9.addActionListener(listener); Button0.addActionListener(listener); astrButton.addActionListener(listener); boundButton.addActionListener(listener); [/code]

Use code tags currently it looks like a mess I doubt anyone would feel like even looking at it. All you need to do is put your code inside:- [noparse] [code=java] // your code here [/code] [/noparse]

Now assuming your File format is of the type :- [icode] Albert Einstein 0 Stephen Hawking 3 [/icode] You would need to add the following lines of code in your while loop before reading the grades like :- [code=java] . . firstName = inFile.next(); lastName = inFile.next(); num = inFile.nextInt(); …

You could use the Logical (if I am correct) Operators ( AND (&&), OR (||) ) to achieve that. For example :- [code=java] while(status.equalsIgnoreCase("yes") || status.equalsIgnoreCase("yse") || ..) [/code] <EDIT> Three posts in a minute on the same thread, thats the first time I have seen it.

Most probably the issue is your tomcat running on port 8080, chances are you most probably have a firewall which is blocking that port from being accessed from outside. Also some networks tend to block outbound traffic on 8080 port as this is usually an intranet port. You could either …

Using the "root" account for MySQL for normal tasks is not recommended and definitely not a good idea to publish its password on a public forum. Also can you give us the exact stack trace what exception you are getting.

[code=java]public InputStream(InputStream paramInputStream, boolean paramBoolean) [/code] Now I am just guessing here, but I think the paramInputStream parameter is of type Base64.InputStream .
