| | I know this is going to sound basic, but add some breakpoints into areas where the operations are being performed. Then debug the code and add watches to the data variables. By watching each variable, you will be able to narrow down where the problem is, and then post a … |
| | Re: Java: Basics Ok. You need to think about this logically. You must first read the users input. Then split the string of numbers into individul digits - which are then stored in some sort of collection. You then need to iterate through the collection and print out each element. We don't get …  |
| | Re: switch case You might have a better idea if you look at the Java Primitive Data Types and what data they are able to hold. https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html  |
 | I always program my web apps in Notepad++. It's simple and it means you have to type all the code out yourself so helps you learn much faster. As for the whole "View your website" options in different software suites, don't trust them. If you have a quick poke around … |
 | I don't get it....you've out foxed this fox....which makes you extremely bloody foxy!  |
| | Hey, Basically I want to be able to type something like 'editor &' and have an editor of my choice open. Similar to if you type 'emacs &' emacs opens. I was wondering where this information is kept and how to edit it for the desired results. Thank you  |
| | The blueprints aren't instantiated because a blueprint is a design for a building not the building itself. Just in case this analogy has gone too far; Java attempts to mimic the real world using objects e.g. Cars A class is a description of a car. Is defines everything about it. …  |
| | I'd say if you have a good knowledge of Java already it's probably best to just use that. Another option is obviously C++ which if you know Java and C, you will most likely pick up very easily. I don't know if there's a language out there thats better for … |
| | Just to add to the discussion, I believe it is possible to speed up your pc using a USB and ReadyBoost. I have very little knowledge about this however so it may not be possible. Have a go though, right click on your USB in 'My Computer' and select Properties. … |
| | I agree with JamesCherrill, the best way to further your knowledge is to think of a project. Then, go and create it. First try will be shit (pardon my french), but as you continue to develop applications, you pick up the different techniques required. One thing I would say is …  |
| | AhmadHasanSahi, This information is widely available on the internet as these are very common sort operations. I suggest you take a litle bit of time to research rather than asking for others to write your code for you. This is a free help forum, not a development centre. There are … |

| | I am currently creating a MySQL back-end database system and have come across a problem. Whilst building my ERD, I have noticed that one table requires 3 Foreign Keys. Is this acceptable database design? Thanks for all your help |
| | I think I know what you mean. I believe you are asking about the different elements that form an expression. I think for this I shall just list them for you. * This - Dimension Variable * That - Object * TheOther - Function * Something - Parameter It is … |
| | Read this an figured I should add something. DO NOT FOLLOW DEEPMODI's advice!!! Microsoft never take kindly to people downloading their software from anyone except themselves. People have tried and failed repeatedly. So as a reminder, Microsoft Website Only! The last thing you want is to be in a legal …  |
| | Another useful resource is the Kolling and Barnes book which is used in many Java courses. It uses it's own development environment which is designed for teaching java to beginners and the book will take you to an average level of Java programming. If you are interested, the book is … |
| | Just to kind of echo what JamesCherrill has said, it is impossible to access a machine without an IP address. The entire point of an IP is address is to provide a reference to a machine across a network. It is literally impossible to find a machine without it's ip. … |
 | I believe that you are in my CS class at Hertfordshire judging by this post. Your answer is clearly laid out in the practical 9 pdf on the hompages site. Look under heading "UselessHTTPServer05". |
| | You said your new to Java. If thats the case then I would definately recommend not starting out with such an ambitious project. |
| | It depends on the nature of the website. However you can work out most of the requirements within 5 minutes. 1. How much space does your page take up on your computer? ::Thats the start of your storage requirements 2. How many people will be visiting the page? ::Increased traffic … |
| | Google displays results based on two main qualities. First is, it looks at what pages link to your page, it examines the importance of all these sites. It then looks at all the sites that link to those sites and examines the importance of those sites. Bigger, more influencial sites …  |
| | That is truely amazing. Not that he can write code, because realistically, anyone can do that given the time and resources...but that someone was willing to give him a chance, that's inspirational. Thank you for sharing this  |
 | It would be interesting to see more of a following for the Hardware/Software area of the forum. Obviously it would increase the knowledge base that would become available to the users of Daniweb. I think the reason there has been a demise, is the movement in education away from Hardware …  |
 | What you've done is great, you have literally missed one tiny detail. The replace method in String returns a new String object. Currently you are calling the method but not putting the result anywhere. So when you return the variable 'string', you return what you gave it. Try using `string … |
| | Re: Bluej I'm assuming that because you are using BlueJ, you are in your first semester of a Computer Science Course or related course. On this assumption I am going to recommend you talk to a tutor or to some class mates as the question seems to be related to a specific … |
| | Ok so I'm writing a program that outputs text to a file. Currently, I am writing it to a .TXT file for ease and convenience. Ideally, I would like to output some of the information so that it is formatted with Italics. I'm thinking that using a RTF file would …  |
| | There is no need for the If statement to be there. When you iterator through your Collection, you either find the desired item, or you don't. These are your only 2 outcomes. 1. Item Found - Return the Item object, method stop executing when a value is returned 2. Item …  |
 | ok so your going to need a loop surrounding your statements so that 3 items can be selected private String[] mainArray = new String[10]; private String[] threeStrings = new String[3]; public void getThreeRandomStrings() { Random rand = new Random(); for(int i = 0; i < 3; i++) { threeStrings[i] = … |
| | Re: I NEED HELP!! Ms.toumi, thsi forum is not designed for people to do your work for you. If you need help, then show us something you have already done, little bits of code that you have started to develop towards your solution. Do not just ask for help and give a description of … |
| | Cheaper than books, try [this](http://www.w3schools.com/) website. It's free and has a lot of good starting points. If your looking for inspiration and to see some cool design ideas/code, visit [css-tricks](http://www.css-tricks.com). It's run by a guy called Chris Coyier and he usually posts some pretty interesting guides about web programming. If …  |
| | Well computer DateTime is actually stored at a 64bit number. This number started on Jan 1, 1970. so for you ID you can use this 64bit number as it can uniquely identify a record. It can also be used (with some additional processing) to give you a DateTime. 2 Birds … |
| | ghosh22, What vjproduction is saying, is that the problem that you have posted is long and complex, and you haven't actually made a start yourself. This forum is designed for smaller, more specific problems. You have posted a specification for a project and are expecting experienced web designers to do … |
| | Thats a lot of data to analyse, but after a quick look, I see you haven't closed the socket. You have closed the BufferedWriter that writes along the socket but not the socket itself. I don't know if i'm 100% correct here but it's all I could think of. Good … |
 | I don't think there is a built in function of Eclipse that offers this, however they may be a plugin floating around out there. I'd have a look for that |
| | By default, when you declare and create a new array, each element is set to 0. So, using this logic we can conclude that if you remove a 0 from the array, Java replaces it with the default value, 0. There are two simple options. 1. Bite the bullet use … |
| | I'd recommend getting used to programming command line programs in Java before hopping into GUI's. I recommend this because a lot of the underlying functionality is key to writing a good program. If you start at GUI's, you tend to focus more on interface design and less on the program … |
| | Re: nubie helpout If your a beginner I'd recommend buying a book on Java. Something like [Sam's 24 Hour Java](http://www.amazon.co.uk/Teach-Yourself-Hours-covering-Android/dp/0672335751/ref=sr_1_1?ie=UTF8&qid=1385516161&sr=8-1&keywords=sams+24+java) as it will give you the basic starting blocks for the language. Going straight into a project such as a POS system is a bad idea as it requires a higher level of … |
| | If you really wish to find out then declare a float and a double. Then print them to the screen. e.g. public class Test{ private float myFloat; private double myDouble; public static void main(String[] args) { System.out.println("Float: " + myFloat); System.out.println("Double: " + myDouble); } }  |
| | Trying to return Multiple Card objects from a hashmap Currently using the following code private HashMAp<Integer,Card> allCards = new HashMap<Integer,Card>(); public Card getAllCards() { Collection col = allCards.values(); for(Card c: col) { return c; } } This works but only returns 1 Card object from many. How can I change … |
| | Basically I am creating a web page that is going to eventually load content dynamically using PHP. Right now I am constructing the HTML/CSS for the page so that the design is complete. My problem is that when I add x amount of content to my page, the content simply …  |
| | Hey guys I recent wrote the deal or no deal game in Java for fun. It currently operates using a Command driven interface where users input numbers based on textual feedback. My aim is to develop this into a full GUI interface, however, I have not met GUI's yet in … |
| | I agree with JamesCherrill. You can't measure the performance of an algorithm without first understanding the algorithm. It's like asking someone 'How long is a piece of string?' Without the string, we cannot tell. |
 | If your interested in different css styles for different screens, I would recommend the [CSS Tricks](http://css-tricks.com/css-media-queries/) website. This is also a great website for loads of different web design tricks. Hope you find it useful |
 | The one that Microsoft usually recomments is MalwareBytes Anti-Malware as can be found [here](http://www.malwarebytes.org/) |
 | Thing that springs to mind is that you've got other applications running that maybe you didn't realise are running. Some programs start at System boot without you even realising. They then take up processing power and you experience a lag in your games. This would also explain the large amount … |
| | Re: Java classes Basically what you are doing is putting a piece of information into that method. In this case your putting a `Person` object into the `hasDriver()` method. Now `drive` is how you reference the `Person` object. so if Person has a method in it called `getName()`, you would say `drive.getName() A … |
| | Ok the answer is check to see if the cell in the Array is null before trying to access if. int[] anArray = new int[10]; for(int i=0; i < anArray.length; i++) { if(anArray[i] != null) { System.out.println("Value: " + anArray[i]); } } |
The End.
