kandi X-RAY | try Summary
This API is a Java 8 implementation of the Scala Try API, originally implemented by Twitter Engineers and later added to the Scala Standard Library. The Try type represents a computation that may fail. If the computation is successful it returns the value wrapped in a Try.Success otherwise the java.lang.Exception wrapped in a Try.Failure. In order to use Try you need to call the Try.apply(FailableSupplier) method providing a lambda with the same signature used for a common java.util.function.Supplier. Indeed FailableSupplier is just a java.util.function.Supplier with a throws Exception added to its get method. Note that I'm not saying here that the try-catch approach must be abandoned in favour of Try-Success-Failure. Indeed there are cases where you would use the traditional try-catch pattern but, in general, I think this API provides a more fluent interface to deal with exceptions.

QUESTION
I've come across an issue of trying to fade the edges of the background image of a div so that it looks like it's blending with the background image of the full site (so the background image applied to the body).
...ANSWER
Answered 2021-Jun-16 at 02:49You can use the background as gradient where the edges are rgba(0,0,0,0). This way it will smoothly blend with background. But this will not work for images. For images You will have to a div of background color and rgba(0,0,0,0) in gradient with color facing outward.

Recently I've been coding a clicker game and now have run into a problem with the onclick function. What I'm trying to do is on the first click, have it change into certain text, and on the second and third clicks change it to a different text. However, on the fourth click, I'd like it to disappear.
However, it disappears on the third click instead of the fourth click. The third click is supposed to show more text, and then call a function and vamoose. It just disappears. Here is my code:

I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.

The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py

I am trying to use next-firebase-auth package to manage authentication in my next js app. Before messing around, I wanted to run the example. However, I could not find proper explanation for the fields required in the .env file.

QUESTION
I have 2 arrays. I need to show only data which does not match with the second array.
...ANSWER
Answered 2021-Jun-16 at 01:12You cannot compare two different objects using includes in javascript, because includes uses ===. Only references to the same object will return true using ===. You'll need to write a custom function that runs through all of the keys of your object and compares their values between your two arrays.
This article explains some techniques for comparing two objects: https://dmitripavlutin.com/how-to-compare-objects-in-javascript/
QUESTION
This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.
And manifest.
uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
is written.
Please let me know the solution. And this content is written with a translator, so the sentence can be strange.
when you press finButton, the logcat is shown below.
The code corresponding to the 116th line is this.
...FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);
ANSWER
Answered 2021-Jun-16 at 01:47Try with Context.MODE_APPEND or Context.MODE_PRIVATE instead of Activity.MODE_WORLD_WRITEABLE
