url - How to add progressbar to display download status in Java? -


I am using an external library to download files from mega but to display the user's download time Requires a progress bar. I've read articles related to a lot of progress bars on stack overflow but the problem is that I do not know how long it takes in my code to add a progress bar.

How do I add the progress bar to display the download status? 

  Try {URLConnection urlConn = new URL (file_url) .openConnection (); Print (FILE_URL); Is = urlConn.getInputStream (); While ((read = is.read (buffer)) gt; 0) {cos.write (buffer, 0, reading); }} Finally {try {cos.close ()} if (is! = Null) {is}. }} Finally {if (fos! = Null) {fos.close (); }}} Print ("Download Finished"); }    
 
 
 You can create a progress bar dialog and show it actively , And then your  swingworker . Swing Worker  is a type of movable object (it will be executed behind your main thread)) and especially graphic elements ( publish  their To update the changes) is visualized, because it works.  
 Take a look at this stackover flow question:

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
