So let us start by looping through the list for the first element: for(inti=0; i < b.size(); ++i) {// something with b.get(i)} Next we need the second element. If, forj, we start at index0again, we would need to check whetherjis equal toi. In addition, when we get to ...
in Java, you have to declare how many elements the array holds initially. And once this is set, it cannot be changed. However, with an ArrrayList, the number of elements in the array isn't set. You can add elements to the ArrayList as you please...
so I can see if they have collided. I wrote the following but all I get is 'no collision' even when they have collided. I put it in two methods. My assumption is that since both loops are looping from the same point are they just constantly ...

The biggest "problem" with Hashtables is that, when looping through their contents, the items don't [often] come out in the same order you put them in (they are "ordered" by the calculated, Hash values). HTH, Phill W. Jan 5 '07 #15 HKSHK Hello vbnewbie, vbnewbie schrieb: Co...

Below is the dataweave. I have to loop through all the items and create java.util.Map, but since it is looping through it is considered an array and adds the square brackets. This is happening at the code which I have in bold. I could convert to string and use the replace command to...
There is a short cut way to convert ArrayList to a generic list instead of looping through items.Generally this is what people do :omg: List orders = new List(myArrayList.count); foreach (WarriorTrading.Order order in myArrayList) { orders.add(
returns false (thus e.g. ending a for(:) construct). That means that for example looping through an arraylist and removing the second-to-last element on its iterator results in the while loop ending as normal instead of the expected and according to javadoc spec required ConcurrentModification...
