 | Hi. I have a little problem with my code. I want to cast a complete arrayList to a different type, but java wont let me... Here is a compressed version of what is happening: [CODE] //The interface I use. public abstract interface Drawable{ //some methods } //A class that is …  |
| | Hi. I am trying to make a script that will print out numbers in rapid succession after working a little with them. The script needs to write them in the console one after another (next line). The code works just fine when I do not utilize multi threading, but when … |
| | Hi! I am looking for a laptop with DirectX 11. It needs to be nVidia graphics, and preferably light. Price is not really an issue as long as these 2 criteria is fulfilled. I have looked at the Vaio Z, but they only got dx10. Other than that, they are … |

| | Hi! I am working on an program that basicly needs a large list. The program works fine untill i comletely fill up the "List<Object>" type. And no, it is not due to lack of ram. The program tries to add more than System.Int32.MaxValue ammount of objects. I have thought about … |

| | "where row = '4'"? It is hard to interpret your code. Sounds like you have a sql-issue, not a C# issue. |
| | I'm developing a web-program that needs to check a whole bounch of potentially faulty http-links. Now, I have found a way of doing this, the only problem is that it relies on try-catch, not in it self horribly bad, but the time it takes to check the links is extremely … |
| | Hi. I am working on a multi threaded program (game renderer). What I want to do is to loop through my threads and get a boolean value that tells me if the thread is done rendering or not. If all the threads is done, I want the code to go … |
| | I believe that would be correct. Since B get everything from A, and then changes booleanA. So when example gets everything from B it will have the values: False, true, true. |
| | Please use CODE-tags to post code. It makes it a lot easier to read! Also, try to write better English. It is hard to understand what you write. |
| | Hi. I got a noobish question: Is it possible to return an array "directly", so, something like this. [CODE] public int[] getArray(){ return int[]{this.intA, this.intB}; } [/CODE] I know I can just make the array first. But does this not use unnecessary cpu time and memory? This is going to … |
| | Re: math.pow Then write #*7; not "# to the power of 7". This is basic math. Consider learning that before Java :) |
| | "while (validInput == false)", it would be more esthetically pleasing to write "while(!validInput)". [CODE] public static float calculateInterest( float mortgage, float interest, int period ) { // Post: float intRate = interest / 100; return mortgage * intRate * period; } [/CODE] This can be made more efficient by writing: … |
| | Can't you just flip the array when it is sorted? Sure, it is not optimized, but it works. |
| | Hi, I'm working on a game for a homework assignment. We are a group of 4 and basicly got the game running now, but we got issues with the rendering/drawing. I use BufferStrategy to get double buffering, and i have a custom draw-loop in a canvas. What this does is … |
| | Hi, I'm trying to set a double-value, but somehow it does not take my statements. This is what I got: [CODE] public double getDouble() { return aDoubleValue; } public double getAnothertDouble() { return aDoubleValue2; } public void myMethod(MagicObject a) /* Some magic */ //Here lies the problem: (FX is a … |
| | Please give us some code. It is a lot easier then. |
| | Here is what you do: get all your integers into a int array (like this: int[] intArray = new int[count]; Make sure to count your integers first (run trough the file and count them)). Ok, so next you want to use something that is called modulo. The operator you use …  |
| | Hi. Im working on a text-based "game" that uses strings to generate maps. So I need to split these strings into bits that i can work with, but somehow the .split method kills the white space in my string. How can I get around this? Of course I can force … |
| | The problem might be that there is 11 digits in you value. Regular integer values only takes 10, so you might get a memory loop or whatever it is called where the value gets to high, so it starts at the bottom and works it was up from -2,147,483,648, or …  |
| | Hi. I'm working on a encryption thing. For it to run properly i need jsp to be able to handle big integer numbers (10^15 and higher). The long variable gets me to about 10^9, but that is not enough. I cant seem to find a way to force jsp to … |
