Why instance variables are not initialized before constructor creation. What happens if they are initialized at the class loading itself [closed] solved Why instance variables are not initialized before constructor creation. What happens if they are initialized at the class loading itself [closed]
You can do it with min and zip quite easy: l1 = [1,2,3,4,5,6] l2 = [10,20,5,8,30,25] l3 = zip(l2,l1) print(min(l3)) Output: (5, 3) Comment As mention in the comment by @sshashank124 it is important that the first list is the list you want to find the minimum. In this case it would be l2 that … Read more
To get the sum of the elements as your question states, you can use streams. int sum = history.stream() .filter(his->his.getRes().equals(“Vundet”)) .mapToInt(his->his.getWins()) // assuming this getter exists. .sum(); 2 solved Get the sum of elements of an ArrayList
@AndrewHenle commented: If you want to compare numbers with different numbers of digits and not strings, you need to convert the strings to actual numbers. As it is clear from your comments that you want to compare the numeric value that is contained in the strings, you need to do just that — convert the … Read more
A simple way to do it is to iterate over the string, that will give you each letter separately: alphabet = “abcdefghijklmnopqrstuvwxyz” for letter in alphabet: print(“a” + letter) solved Adding first character of a string to each of the other characters [closed]
In your texture sample call (in the shader), you need to set your magnification filter to ‘nearest’, instead of ‘linear’, like so (assuming your sampler is declared inline inside your shader): constexpr sampler textureSampler (mag_filter::nearest, // <– Set this to ‘nearest’ if you don’t want any filtering on magnification min_filter::nearest); // Sample the texture to … Read more
html does not have variables by itself. In order to save data you will need a programming language like PHP or GAE with Python for example. You can either save the data into a database or into a simple file using php. You can then load the data from the file into a table with … Read more
Another option is to parse the XML, and use the OutputKeys.INDENT option of the Transformer class to output the XML formatted. The following example Source source = new StreamSource(new StringReader(s)); TransformerFactory transformerFactory = TransformerFactory.newInstance(); transformerFactory.setAttribute(“indent-number”, 4); Transformer transformer = transformerFactory.newTransformer(); transformer.setOutputProperty(OutputKeys.INDENT, “yes”); StreamResult result = new StreamResult(new StringWriter()); transformer.transform(source, result); String xmlOutput = result.getWriter().toString(); System.out.println(xmlOutput); … Read more
instead of nowh.before(enh) && nowh.after(sth) use nowh.before(enh) && nowh.after(sth) && sth.before(enh) || enh.before(sth) && !(nowh.before(enh) && nowh.after(sth)) Apart from that I think Calendar class is supposed to be used differently I assume… solved How can I compare two hours in java?
It looks like you are trying to get a count of all users who registered on a certain day. If so, I think you are best off using the group keyword to group together all users by registration date. You can then create a new anonymous type to contain by the date, and the count, … Read more
You can pack your application in a .jar, actually a zip file with inside .class files and resource files. Those resource files, like your images, can be taken with getClass().getResource(“path/x.png”) or getResourceAsStream. The path is either package relative or absolute: “/abc/def.jpg”. These resources must be read-only (as they are inside the .jar). However you may … Read more

NO, your function does not behave the same as memset. Your function sets a pointer to NULL and memset sets the values of the data to the value supplied. Different things altogether. 3 solved behavior of memset
