I’d advise against using == to test string equality. Use String.Equals() instead. You can also do this in one statement using Linq: if ((new [] {string1, string2, …}).Any(s=>string.equals(s,”No”,StringComparison.CurrentCultureIgnoreCase))) { DoStuff(); } This will DoStuff() if any of your strings are equal to “no” ignoring the case. See String.Equals() and Enumerable.Any() for further reading. It should … Read more
Those aren’t bitwise operators per se. They’re operators, and each type can define for itself what it will do with them. The & and | operators map to the __and__ and __or__ methods of an object respectively. Sets define operations for these (intersection and union respectively), while lists do not. Lists define an operation for … Read more
In Groovy variable/expression substitution inside of strings (interpolation) only works with certain types of string literal syntax. Single quote syntax (‘content’) is not one of them. However, if you replace the outer single quotes with double quotes (“content”) then you should get the interpolation effect you are looking for: def sDescription = “foo” def sedCommand … Read more
The code to set the value is actually executed in Form1‘s context only. Since you made it a static field without understanding what you are doing that initialization code does not get a chance to execute and code in Form2 happily sees the null value. So says my psychic debugging about this ill-defined problem statement. … Read more
Getting value from the request, you should be putting a value to a request. This code request.getAttribute(“testvalue”); is getting a value, but that code request.setAttribute(“testvalue”, value); is putting it. This is because you want to avoid using the HTTP session. solved Send value from 1 jsp to another jsp
I am not going to give the whole code as it is not that difficult to write. Just write is as you described in your question, just specify the parameter how (viz pandas.DataFrame.merge). The default is inner which causes the lost rows as it merge only on rows that exists in both dataframes. From your … Read more
You should be able to perform all the steps weston mentioned in his answer, otherwise, I’m afraid me just giving you the code won’t teach you very much. Instead, I will provide you the pieces mentioned in the other answer. You want a class that represents the course, with name and points fields This is … Read more
There are several concrete classes that implement the List interface in the java.util package. Looking at List‘s javadoc lists a few of them under the “All Known Implementing Classes” heading. You’ll find the implementations there. solved Where can we find the definition of methods present in the interfaces given by java.util package
As others have stated, the problem is due to the way floating point numbers are stored. While you could try to use workarounds, there’s a better way to do this: Animation. In __init__: self.grid.opacity = 0 anim = Animation(opacity=1) anim.start(self.grid) solved Float comparison (1.0 == 1.0) always false
There are several issues in your code. First of all, all the fields of your edit struct must be exported which means you should capitalize the first letter of every fields. Just like the following: type edit struct { Id Values } The data type of of key of the Values field must be string … Read more
If you are getting error messages from the API like this: {“message”: “”, “code”: “api.404”, “data”: {}, “success”: false, “error”: false} try requesting each UUID seperately and once you have gotten a good response, try running it with your program. It seems that the API caches UUIDs that have been asked for the first time, … Read more
You are missing the map operator here. You have to add map operator to the stream processing pipeline before collecting it. Here’s how it looks. objList.stream().map(Obj::val).collect(Collectors.joining(“.”)); solved Concat parameters from object list
