HI Everyone! So this is my first post here and I'd like some help from you.

So this method should return all priority Notes but they should be sorted by their priority like the notes with priority 1 comes first and after that priority 2 and so like this. This in an ArrayList
and I've stopped here because I can't figure out how to do ..

Could you please help me with this sortation?

Thanks in advance

Java

<pre>public PriorityNotes[] getPriorityNotes(){
	
PriorityNotes[] PriorityNotes = new PriorityNotes[notes.size()];
	
PriorityNotes = notes.toArray(PriorityNotes);

int i;

for(i = 0 ; i < notes.size(); i++){


}
	
return PriorityNotes;}

Where is the ArrayList? All I can see in your declaration is a simple array. You should create a proper ArrayList and then use Collections.sort[^] to sort it in order.

My ArrayList is above all methods ... I've created it
here I just posted this method because I thought you'll understand that I created it
So could you explain how to use the

Collections.sort[^]

?

and where to put this? inside the for loop

What Richard meant was, that you should only call the sort function on the ArrayList object of yours. Also, you have not shown the structure of your PriorityNote object, does it contain a priority field in itself, or do you assign a value on runtime? If that is a built in field there, then just call the sort function, and to even control how an object is sorted, read java - Sort ArrayList of custom Objects by property - Stack Overflow

Follow the link I gave you, it explains it there. You do not need a loop since this method sorts the list in place.

I don't have a field called private Priority_Notes , it shouldn't be it's the task from the class diagram
Ok here I'll give you my fields to see which I have

Java

private int  numberOfNotes;
private ArrayList<Note>notes;

and that's all fields which I have

Since we have no idea where the crash occurs, or what code it is trying to execute, it is impossible to guess.

means you are trying to access an address that is not in your address space. You will need to use the debugger to find the actual code that causes the error.

I see two equally meaningless posts about "a priori" and "bayes". It seems that an assignment in the statistics / applied maths course has just been given and what does everybody do? Look through their course notes, refer to a text book or do some searching on Google, nope... ask Code Project!
