Thread: converting array into arraylist

Currently i have:

int[] test = {1,2,3,4,5};
ArrayList<Integer> ar = new ArrayList<Integer>(Arrays.asList(test));

this gives me the error:

error: no suitable constructor found for ArrayList(List<int[]>)
        ArrayList<Integer> ar = new ArrayList<Integer>(Arrays.asList(test));
                                ^
    constructor ArrayList.ArrayList(Collection<? extends Integer>) is not applicable
      (actual argument List<int[]> cannot be converted to Collection<? extends Integer> by method invocation conversion)
    constructor ArrayList.ArrayList() is not applicable
      (actual and formal argument lists differ in length)
    constructor ArrayList.ArrayList(int) is not applicable
      (actual argument List<int[]> cannot be converted to int by method invocation conversion)
1 error

What i want to do is make a method that takes an array as parameter and returns an arraylist with the same elements.

bleh, thanks anyway

Then do what kenster421 said. Iterate through the array and add it all to the ArrayList.

One small fix though. Make the parameter an "E" array. (E[] array)

public ArrayList<E> test(E[] array) {
    //Iterating code
}

Be careful when using generic types with plain arrays though. They hold primitives as well as objects, which can cause problems.
