I have a dataset that looks basically like this. (Not real links)

Trying to make it so if the user types "end", in the second input which is "Enter the first name of student", the loop automatically assigns each object in the array the attributes of "null" for id and name, and 0 for age and id, as well as breaking the outerloop. However, I get the error java.lang.NullPointerException. Any help would be appreciated.

From this I know that the WriteConsoleOutput() function needs a const CHAR_INFO * argument and I am trying to figure out if there is a way for me to use the code which I have supplied or do I have to use raw pointers? https://docs.microsoft.com/en-us/windows/console/writeconsoleoutput The error tells me that I need to either convert the type which I supplied or just give up on the idea. I tried casting but that ended up nowhere... I am new to smart pointers, so if there is an explaination out there, sorry.

So I'm making a snake game(it's not finished) and I got the vector subscript out of range error. I'm really new to C++ and also very confused. It doesn't say where the error is(it's not in the error list) and the error only shows up at runtime. Since I don't know where the problem is, here is the whole code.

I'm making a while loop which will execute every 1/3 of a second or so (for a Snake game). I want the loop to be able to process Scanner input if there is an input, and if there isn't a user input, I want the loop to perform some default task (move the snake in the last input direction).

I understand that a much simpler way to do this would be to create a javafx program with event handlers, however I just wanted to see whether I could implement this kind of game in terminal for a personal project. Whenever I open a Scanner within the while loop, I have a variable set to a default value. The scanner, if sc.nextLine() exists, will update this variable. Then my loop does its thing. The problem is that even if sc.nextLine() does not exist, my loop waits for an input no matter how I've phrased my code.

If I remove the scanner from the loop, the code executes on a timer perfectly, with the default input, however once I look for user input with Scanner, it pauses.

I have a program that's essentially supposed to be a title screen for a few games. The background is a GIF (I'm not sure if that's contributing to the problem), and I need to have some JButtons that allow for me to run the actual games. The problem is that the JButton only shows up sometimes when I hover over it (and for a split second, at that), otherwise it's invisible. It works just fine, goes to the game and all, it's just invisible.

I've tried to see if the problem is the fact that I'm using a GIF, as well as the paintComponent() method, although, it just didn't show up when I used a JPEG.

Here's the code:

I am trying to run a Cucumber test with Spring Boot and JUnit.

However, I am getting following error when I right click an execute the TestRunner class.

Am I missing any configuration?

I want to achieve a screen that is scrollable(vertically) with the elements inside it. So I placed it on a listview.builder. The thing is, one of the elements is another listview.builder that scrolls horizontally. When I implemented it, element inside the horizontal.builder doesn't show up. Here is what I have so far:

I am trying to make the snake game using OOP. OOP is a new concept to me, as I typically use functional programming.

I have a timer and when it executes it should paint the snake and the food.
