Since this is homework, it would be a bad idea to write the code for you. So ideally, what you need to do, is get the words that fit into the criteria (that you mentioned) and store them in a list. Then take the length of the list. After that, you can divide the length … Read more
It is not only OK; I’d even recommend it, especially if conditionB is relatively expensive to evaluate. For instance, here’s an alternative way: if(conditionA) { //do A stuff } else if(conditionB && conditionB1) { //do B1 } else if(conditionB && conditionB2) { //do B2 } else if(conditionB && conditionB3) { //do B3 } Let’s say … Read more
Your triple store contains triples spo (subject, predicate, object). A query against a graph so stored may have to traverse a lot of the graph to find nodes that match your query. AllegroGraph can store indices that make that traversal faster: finding all predicates that match first, for example, and the subject and object nodes … Read more
I’ve never used any system to migrate apps between platforms. I code them natively if needed, adjusting UI/UX as expected between platforms. Having said this, for what I’ve heard in a conference where some guys from Apportable explained. They are slowly building up their system. But, as you can imagine, it’s not that easy. On … Read more
Using collections framework in Java, a developer has to use loops and make repeated checks. Another concern is efficiency; as multi-core processors are available at ease, a Java developer has to write parallel code processing that can be pretty error-prone. To resolve such issues, Java 8 introduced the concept of stream that lets the developer … Read more
One thing you could do is extract all numbers, then use the second one: my $astring = “cool more 23423 random words of 1234 random other [wordssssssss] 23”; my @numbers = $astring =~ /[0-9]+/g; print “The second number is $numbers[1]\n”; 1 solved Take second of three numbers from a line in a file [closed]
If I understand correctly, you want all calls to sub (or rather _Z3subP7AStructii) to actually be calling your _sub function instead? The problem is that when the “client” calls some_astruct->sub(…) it doesn’t actually call _Z3subP7AStructii directly, and therefore your _sub function won’t be called. In other words, the “client” doesn’t have a call to _Z3subP7AStructii, … Read more
Use PreviewMouseDown event instead of MouseDown, I guess it would make it work. 0 solved How to add mousDown event in chromium browser c# wpf
Consider Apollo’s comment and google it. This is not only a java principle but a generall programming principle. You’re creating a new Answer Object. Let’s look at this example: public class Answer{ // The class private String answer; // internal variable only visible for the class public Answer(String answer){ // This is a constructor this.answer … Read more

I Used Random function in MVC, and Solved this Problem With Following : Firstly created a random String Generator: private static Random random = new Random(); public static string RandomString(int length) { const string chars = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”; return new string(Enumerable.Repeat(chars, length) .Select(s => s[random.Next(s.Length)]).ToArray()); } Then created a random Number Generator: public static int randomNoGenerator() … Read more
Haven’t used C++ in a while but i think it should look something like this if(x%2 == 0) { std::cout << x << “is even\n”; } else { std::cout << x << “is odd\n”; } your errors are because you were basically saying cout << x; “is even”; which doesn’t make sense to the compiler … Read more
The only problem with MATLAB, for a beginner, is that it is really expensive. Some universities buy it without the Image Processing Toolbox, in which case it is not so useful. Octave is well supported by the open source community, that is another alternative “Processing” is a language that is easy to learn and powerful. … Read more
Hey there and welcome to StackOverflow AND Android development. In order to open the contacts screen, you need to capture the OnClick event for your button and create an intent to open the contact screen. Something like this: Button myButton = (Button) myLayout.findViewById(R.id.myButton); myButton..setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Intent intent= new … Read more
All you need to do is remove the < and > characters: SELECT r1.rnr, r1.anaam FROM regisseur r1, regisseur r2 WHERE r2.anaam = ‘input last name director’ AND r1.gdatum < r2.gbdatum Here’s a working demo on SQLFiddle. Presuming you don’t have a good reason to SELECT from regisseur twice, this can be further condensed down … Read more
