It’s a very subjective question, but Unity sounds like what you’re looking for. It has support for Boo as a language (although it’s not at the forefront of Unity usage). Boo isn’t Python, but is similar enough for you to carry on your knowledge of Python with you, and Unity is a solid engine for … Read more
You seem to have the assignments reversed, public ChangePlane(String name, int[] array1){ this.name = name; this.array1 = array1; x1 = array1[0]; y1 = array1[1]; x2 = array1[2]; y2 = array1[3]; x3 = array1[4]; y3 = array1[5]; x4 = array1[6]; y4 = array1[7]; } Assuming you are passing an int[] array1 = new int[8]; (since array1[7] … Read more
PizzaT array[] = new PizzaT[2]; //Would this be an instance? No, this is an array of PizzaT PizzaT pizzaList = new PizzaT(” “, “”, -1); //Would this be an instance? Yes, this is a PizzaT instance PizzaT(String n, String d, int m) //This must be the constructor Yes. A constructor looks like a method but … Read more
I don’t know what initial values b, x, w and y got so I just initialized them somehow .. But I think you want something like this: public class HelloWorld{ public static void main(String []args){ int z = 26; int b = 0; int x = 1; int w = 2; int y = 1; … Read more
Read the file sequentially – thats the easiest route. Then randomly shuffle the collection. Actually, another question. Could you use math.random() to look at the lines of the text file and if, lets say, the line 5 comes up then you remove it from the parameters you set for math.random()? It would pick from 0-9 … Read more
Try the following: long result = a.get(0) + b.get(0); Then deal with result solved Add to integers stored in LinkedList [closed]
You should be able to cast DBObject to one of it’s implementation (see all implementations here : https://api.mongodb.com/java/3.0/com/mongodb/DBObject.html), in this case BasicDBList, which extends ArrayList , so you can use all methods from arrayList there. Mongo mongo = new Mongo(“localhost”, 27017); DB db = mongo.getDB(“test”);// Use DB DBObject allQuery = new BasicDBObject(); DBCollection collection = … Read more
Just a note, the first commenter is correct, you probably could have found this through a bit of Googling, but here’s the answer as best as I can explain it: Let’s take that code: Random random = new Random(); The first random just says what type of data the variable is going to store – … Read more
The best way to handle this would be: @RequestParam(name=”currency”, defaultValue=”EUR”) String currency or @RequestParam(name=”currency”, required=false) String currency In second case your should check the existance of currency in your in your controller. solved How to handle requests without or with incorrect query parameters [closed]
You can use a StringTokenizer to do this. Here is an example program that you can run to see how it works. If you want to read from a file then you need to learn how to turn the file into a String, then you just pass that string into the makeWordItemsFromString method. import java.util.ArrayList; … Read more
Write a program that takes an array/arraylist of integer and finds longest sub array/arraylist whose entries are equal [closed] solved Write a program that takes an array/arraylist of integer and finds longest sub array/arraylist whose entries are equal [closed]
i agree with @shmosel solution. But it’s true just when second number has only 3 digits. boolean compareTail(long one, long two) { int digits =(int) Math.log10(two)+1; long formated = one % ((long) Math.pow(10, digits)); return formated == two; } 0 solved how to test if Long ends with a number pattern on JAVA?
Yes, you can do it with a regex. One way to do this is to check if for each row you read, you have digits only, and add a constraint for the number of digits. The digits part can be done pretty easily, using a “/d” while the number of characters to be used is … Read more
Actually from the example that you provided I can see that you don’t understand concept of object programming and even concept of functions. So please, start from begining. And if you want to print carry variable in method user() then you must change this method like this: void user(int a) { System.out.print(a); } and then … Read more
First of all, parsing XML by hand is nothing but inviting bugs and gotchas!. Since you must do it without standard parsers and want a tailor-made parsing for a specific XML, here is something you could do to get rid of unreadable code(at least). Now, talking about O(1) space complexity. Assumption is that the XML … Read more
