问题 Alright so I am an intro student in a programming class and I am trying to test a catch statement of a NFE. I don't know how to format the code properly, but here it is. import java.util.Scanner; public class Geo { public static void main(String[] args) { try { Scanner inp = new Scanner(System.in); System.out.print("Name?"); String name = inp.nextLine(); System.out.print("Number?"); double num = inp.nextDouble(); System.out.print("Integer?"); int num2 = inp.nextInt(); } catch

问题 After creating our new system in Vue with babel, I have started testing compatibility towards older devices. Our babel is transpiling the source down to es2015 together with webpack. I have now tested with browserstack against both Ios & android. Newer OS works on both platforms. However on android phones that use the default browser, I get an error in sentry stating; Duplicate data property in object literal not allowed in strict mode It does not give me any hints on where this might be thus

问题 I think there's some kind of non-fatal bug in my script that's not allowing me to a/ debug the script with Firebug and b/ causes Firefox to constantly display a Connecting...

问题 So, i'm trying to write the following function in scheme, and to be able to run it on DrRacket. The problem is as follows, make5 - takes two integers, and returns a 5-digit integer constructed of the rightmost 3 digits of the first input, and the leftmost 2 digits of the second input. For example, (make5 561432 254) would return 43225. Negative signs on either input number should be ignored - that is, (make5 561432 -254) would also return 43225. If the first number has less than three digits
