"I am not able to catch NumberFormatException properly, because of this my onClick is not working

Asked 2019-Jun-30 at 02:32

I was trying to build a simple app that takes the plain text and no of lines as input and convert the plain text into cipher text using the rail fence ciphering technique. I was taking no of lines input from user and convert that string input into integer by casting. As i was doing it, it shows NumberFormatException. I wrote the casting line inside the try block and there after the scope of that variable is limited such that my encryption() method is not able to access it. What can i do as my onClick function is not producing the correct desired cipher text? The button behaves like it was never clicked.

I have tried creating that variable outside the try block and then typecasting it inside the block, i also made that lines variable final as it was accessed within the class. Then it asked me to initialize the variable, I have done that also but it does not seems helping me.

I was taking no of lines input from user and convert that string input into integer by casting. As i was doing it ,it shows NumberFormatException.

That is because you're trying to read a string from an EditText with no input yet as integer which is not a valid number with the following code (see the comment):

Recursion in Javascript not working (CodeWars questions)

Asked 2019-Jan-25 at 09:11

I've been working on a Codewars question for a minute now. Im pretty much done with it if I could get this recursion working in my function. It supposed to be a depth first search, but after failing for the first time the recursive calls do not execute. I will point out the problem area. https://www.codewars.com/kata/path-finder-number-1-can-you-reach-the-exit/train/javascript

QUESTION

JavaFX NullPointerException

Asked 2017-Nov-03 at 08:50

Can someone explain why I'm getting this error and how to solve it? Also try to keep it simple. I'm new to coding. (Also i know the answer to the question exists, but i don't know how to implement it to my code)

It gives NullPointerException error when rows are deleted. Also when the blocks move down, the blocks are still counted as 0 so new blocks go through them. (i guess its only the top row, other rows are working as intended) But the actual error is more important: (but i'd be happy if you help to solve this too)

You are trying to access a shape which is null.

In your case, if you look at line 70, you are trying to perform scene.setOnKeyPressed, but scene is null.

You are calling in 2 places the moveOnKeyPress method. Where your problem is calling this method at line 147, where you do shape.a.getScene(). That call to getScene() is null.

Furthermore, if you look where you call CheckDown, you have them in 2 places, but your problematic call is at line 60.

Not sure what you do at line 48 (Shape a = TetrisHolder.createRect();), but I suspect there might be something wrong with setting up the scene

What I did here is translate your stacktrace:

It doing good, but when I change to second Activity and after that, I comeback to first Activity and click button "Cancel" -> my App crash. I debug and see myAsyntask is null when change activity.
