• java: how can I create a dynamic array without forcing the type of the values?

  - by ufk

  Hiya. I need to create a dynamic array in Java, but the values type differ from String to Int to float. how can I create a dynamic list that I don't need to give it in advanced the type of the values? The keys just need to be ascending numbers (1,2,3,4 or 0,1,2,3,4) I checked ArrayList but it seems that I have to give it a fixed type for the values. thanks!

• How to display an array's content in colomns, like ls -C does.

  - by Arko

  I wanted to display a long list of strings from an array. Right now, my script run through a for loop echoing each value to the standard output: for value in ${values[@]} do echo $value done Yeah, that's pretty ugly! And the one column listing is pretty long too... I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C).

• Finding the maximum weight subsequence of an array of positive integers?

  - by BeeBand

  I'm tring to find the maximum weight subsequence of an array of positive integers - the catch is that no adjacent members are allowed in the final subsequence. The exact same question was asked here, and a recursive solution was given by MarkusQ. He provides an explanation, but can anyone help me understand how he has expanded the function? How does this solution take into consideration non-adjacent members?

• How can I group an array of rectangles into "Islands" of connected regions?

  - by Eric

  The problem I have an array of java.awt.Rectangles. For those who are not familiar with this class, the important piece of information is that they provide an .intersects(Rectangle b) function. I would like to write a function that takes this array of Rectangles, and breaks it up into groups of connected rectangles. Lets say for example, that these are my rectangles (constructor takes the arguments x, y, width,height): Rectangle[] rects = new Rectangle[] { new Rectangle(0, 0, 4, 2), //A new Rectangle(1, 1, 2, 4), //B new Rectangle(0, 4, 8, 2), //C new Rectangle(6, 0, 2, 2) //D } A quick drawing shows that A intersects B and B intersects C. D intersects nothing. A tediously drawn piece of ascii art does the job too: +-------+ +---+ ¦A+---+ ¦ ¦ D ¦ +-+---+-+ +---+ ¦ B ¦ +-+---+---------+ ¦ +---+ C ¦ +---------------+ Therefore, the output of my function should be: new Rectangle[][]{ new Rectangle[] {A,B,C}, new Rectangle[] {D} } The failed code This was my attempt at solving the problem: public List<Rectangle> getIntersections(ArrayList<Rectangle> list, Rectangle r) { List<Rectangle> intersections = new ArrayList<Rectangle>(); for(Rectangle rect : list) { if(r.intersects(rect)) { list.remove(rect); intersections.add(rect); intersections.addAll(getIntersections(list, rect)); } } return intersections; } public List<List<Rectangle>> mergeIntersectingRects(Rectangle... rectArray) { List<Rectangle> allRects = new ArrayList<Rectangle>(rectArray); List<List<Rectangle>> groups = new ArrayList<ArrayList<Rectangle>>(); for(Rectangle rect : allRects) { allRects.remove(rect); ArrayList<Rectangle> group = getIntersections(allRects, rect); group.add(rect); groups.add(group); } return groups; } Unfortunately, there seems to be an infinite recursion loop going on here. My uneducated guess would be that java does not like me doing this: for(Rectangle rect : allRects) { allRects.remove(rect); //... } Can anyone shed some light on the issue?

  - by Henry

  What's the easiest way to convert a table of values (2D grid like Excel), into a 2D array or struct in ColdFusion? Thought of using dot in the name and eval them to become struct, but AFAIK name attribute of input field can only contains alpha numeric and underscore, and first char must be an alpha char.

• Is it correct to use Array.CopyTo to copy elements or should a for-loop always be used?

  - by Arc

  It's easier to write intArray1.CopyTo( intArray2, 0 ) than the for-loop equivalent, but System.Array does not provide any generic Copy/CopyTo methods. Is it better to write the for-loop? Or is using Copy/CopyTo compiled or JIT'd efficiently enough?
