So, I am trying to save data created in my java program to a new file that the user chooses using JFILECHOOSER
. I got the program to select the save file, but then as it goes to write the data to the file, i get this error:
from the look of this, the error occurs in the countOccurance
methods, but then theres the AWT-EventQueue that throws me off. When I look at the countOccurance
, theres no error which I can see, everything looks good. so I don't know why I am getting the error, except that the it has to do with the NullPointerException
heap class:
My Actionlistner to save a new file:
data[]
is initialized before it is saved, otherwise size
would be 0. Nothing would be saved. size
increases as an element is added to data[]
in the add
function. So therefore size
is the number of elements in the array data[]
.
Question (as I understand it) is: Why am I getting NullPointerExcepttion
Answer: Because, given the code provided, data[] is null.
How is that not an answer to the question? And still is my answer by the way despite of the edit. If this is not deleted as an answer, I will be happy to elaborate.
Please note that it is not necessary for the entire data array to be null. It can be that the element being tested (data[i]) could be null. A way to avoid the exception would be to change the code as follows.
This will ignore the null values in data and count only the non null ones.
AWT-EventQueue appears in your stack trace because the exception occurs on an AWT event (press of a key)

Get the min and max value of several items with Comparable
You should not let BehaviourItem implement Comparable as it doesn’t have a natural order. Instead, implement different Comparators for the different properties. Note that in Java 8, you can implement such a Comparator simply as Comparator<BehaviourItem> orderBySpeed=Comparator.comparingInt(BehaviourItem::getSpeed); which is the equivalent of Comparator<BehaviourItem> orderBySpeed=new Comparator<BehaviourItem>() { public int compare(BehaviourItem a, BehaviourItem..

If you use plain spark you can join two RDDs. let a = RDD<Tuple2<K,T>> let b = RDD<Tuple2<K,S>> RDD<Tuple2<K,Tuple2<S,T>>> c = a.join(b) This produces an RDD of every pair for key K. There are also leftOuterJoin, rightOuterJoin, and fullOuterJoin methods on RDD. So you have to map both datasets to..

The website should be consistent with the Globalcom style guide, as they are the colours and fonts that are being used by Globalcom in different areas already. By having the consistency between the defined style guide and the website’s design, users who view the website will be able to easily identify that it is a Globalcom website, and will be more likely to remember the website if they see the Globalcom colours somewhere else as well.
Fitts’ Law
Download Infofield Driver Download
By using Fitts’ law and making the navigation and other interactive parts of the website larger and easier to mouse over (having them near the edge of the screen, which creates a constraint where the user can’t move the mouse any farther because it’s the edge of the screen), the user will make less errors while using the navigation, and the useability of the website will increase.
Also move the buttons that may cause unwanted actions away from the buttons that are to be used the most. An example is moving the “replay intro” button away from the main navigation menu, so that the user does not accidentally click on it, resulting in the introduction being replayed. This could possibly deter the user from re-entering the site.
