Is there a more efficient way to grow a large array than creating a new one and copying over all the values? Like, concatenating it with a new one? What about having fixed-size arrays stored in another array and reallocate / copy that top-level one? Would that leave the actual values in place? I'm aware of ArrayList, but I need a lot o...
I am attempting to write some test cases for some classes that involve testing the equality of two dimensional arrays of data. Here is my first stab at it: double[][] expected = { {0, 104, 0}, {145.5, 0, 0}, {83, 0, 0} }; double[][] actual = someObject.getArray(); Now, I see that JUnit does not have an 'array...
People I'd like to see if an element at index[i] is not present in a different (or current ) array. So for instance if my array looked somewhat like this [wer, wer4 , wer5 , werp , klo ... Then I would like to see if aExerciseRef.IDE ( which is "sdf" for instance ) does or does not exist at index[i]. I assume I'd have to use some sor...
What is the syntax for indexOf() to go through a multidimensional array? For instance: var x = []; // do something x.push([a,b]); x.indexOf(a) // ?? I want to find 'a' and do something with 'b'. But it does not work... As this method should be iterative itself, I do not presume using any other iteration would be a good thing to do. C...

Hello all. I'm wondering if my method below of comparing an array of strings (or any simple type really) has any performance repercussions. bool AreValuesEqual(List<string> oldFieldValue, List<string> newFieldValue) { if (oldFieldValue.Count != newFieldValue.Count) return false; var list1 = oldFieldVa...

Hi all, Just a quick question really. Say I have a 10x10 array in Java, some of the places in which are not used, and I'm needing to go through all elements as part of a method. Would it be better to: Go through all elements with 2 for loops and check for the nulltype to avoid errors, e.g. for(int y=0;y<10;y++){ for(int x=0;x<10;x...
