I defined List<Integer> stack = new ArrayList<Integer>(); When I\'m trying to convert it to an array in the following way:
I was just looking at the method defined in the List interface: Returns an array containing all of the elements in this list in the correct order; the runtime type of the returned array is that of t
I have a method to build the array for the required type. It works for the primitive types. But when I have arra开发者_JAVA百科y of custom objects it doesn\'t work. So I have tweaked it. But still it
Before Java generics, Collection.toArray() had no way to know which type of array the developer expected (particularly for an empty collection). As I understand it, this was the main rationale behind
I\'m looking for an easy way to clone off an IEnumerable<T> parameter for later reference. LINQ\'s ToArray extension method seems like a nice, concise way to do this.
The following code (run in android) always gives me a ClassCastException in the 3rd line: final String[] v1 = i18nCategory.translation.get(id);
In the code below, I needed to fetch an element, any element, from toSearch. I was unable to find a useful method on the Set interface definition to return just a single (random, but not required to b
Right now, I have: public <T> T[] toArray(T[] old) { T[] arr = Arrays.copyOf(old, old.length + size());
I\'ve got a List collection and I want to iterate over it in a multi threaded app.I need to protect it every time I iterate it since it could be changed and I don\'t want \"collection was modified\" e
