Kirat[ad_1] So you could parse it to a string and get the numbers that way like: int num = …; string numbS = Integer.toString(num); char char1 = numbS.charAt(0); int num1 = Character.getNumericValue(char1); Or you could do it by dividing by 10 and then the remainder of ten: int digit2 = (num / 10) % 10; … Read more
[ad_1] Based on your clarification from the comment, it seems you don’t need no try or catch. But exception handler instead. Just have your 400+ methods have to throw 400+ exceptions – they all will be processed in one handler. P.S. It seems most of SO folks cannot tell a negative answer from negative vote … Read more

[ad_1] You could try using the $.ajax method: $.ajax({ url: ‘/some_server_side_script’, type: ‘POST’, contentType: ‘application/json’, data: JSON.stringify({ username: $(‘#username’).val(), password: $(‘#password’).val(), }), success: function(result) { alert(‘success’); } }); In this example I have explicitly specified the Content-Type HTTP request header to application/json so that the server knows the exact content type being sent. I have … Read more
[ad_1] All your suggestions were valid but this is what actually worked. import Foundation import Alamofire class GreetingObjectHandler { var greetings: [Greeting] = [] init(filename: String) { let fileP = NSURL(string: “http://localhost:2403/users/me”) let jsonD = NSData(contentsOfURL:fileP!) let jso = JSON(data: jsonD!, options: NSJSONReadingOptions.AllowFragments, error: nil) var id = jso[“id”] let filePath = NSURL(string: “http://localhost:2403/users”) let … Read more
[ad_1] First of all, this test won’t work in Java 9 or later. Attempting to compile the String class will give this error: java/lang/String.java:1: error: package exists in another module: java.base package java.lang; ^ On Java 8, I get the behavior you see. Assuming that the tweaked String class is in the same source tree, … Read more
[ad_1] I solved it. My problem was that I had two C compilers installed at the same time, the other one came along with Free Pascal. Found it out through checking every folder in my Path environment variable. Thanks for the replies. [ad_2] solved GCC compiler cannot find stdio.h

Click on the segue arrow between the viewControllers, and set its identifier in the Attributes Inspector on the right. Repeat steps 1 and 2 for each ViewControllerB, ViewControllerC and … Read more
[ad_1] Why doesn’t std::vector or other containers have length as a member variable, instead of a function? Because it would be writable if it was a public member variable. Since it makes no sense to write to the size member of a vector, the designers made the size member private and provided a size() method … Read more
[ad_1] If you are also importing comments.models in posts.models, This may happen due to circular import. Try this: from posts import models as posts_models and post = models.ForeignKey(posts_models.Post,on_delete=models.CASCADE,related_name=”comments”) 3 [ad_2] solved Django +2 ImportError: cannot import model
[ad_1] Because you just declared the function and never called it. Try this: def main_menu(): print (“This is main menu”) main_menu() I hope this helps. Have a great day! [ad_2] solved why cant i get my “def” functions to output text correctly? [duplicate]
[ad_1] on linux go version 1.15.2, i run below code and it spawns a new process that does not die with main. package main import ( “log” “os” “os/exec” ) func main() { cmd := exec.Command(“go”, “run”, “./d”) cmd.Stdin = os.Stdin cmd.Stdout = os.Stdout cmd.Stderr = os.Stderr log.Printf(“Running command and waiting for it to finish…”) … Read more
[ad_1] Just define a Boolean variable and set its value to ‘true’. You only need to run a loop “n/2 times” as the maximum divisor is half of the actual number. So, if the input number is divisible by any value between ‘2-n/2’, set the value of Boolean variable false. In the end, print the … Read more
[ad_1] use .toggle() for example… $(function(){ $(“#red”).on(‘click’, function(){ console.log(‘click on red div’); $(“#blue”).toggle( “slow”, function() { // Animation complete. }); }); }); #red{ height: 100px; width: 100px; background: red; } #blue{ height: 100px; width: 100px; background: blue; } <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div id=”red”></div> <div id=”blue”></div> [ad_2] solved Make div disappear and appear by clicking another div
