![]() ![]() Note: If we don't pass any argument to the toArray () method, the method returns an array of the Object type. Notice the line, languages.toArray (arr) Here, the toArray () method converts the list languages into an array. String array arrayList.toArray(new StringarrayList. It is recommended now to use list.toArray (new Foo 0), not list.toArray (new Foo list.size ()). Here, we have used the ArrayList class to implement the List. ![]() While an object array will work, I dont think its best practice in a strongly typed language. Iterate the array and add each element to the list. You need to use toArray and give it an argument thats an array of the correct type and size so that you dont end up with an Object array. ![]() I want to convert it into an Array and then split it with as delimiter and have abcd,mnop in an array and xyz,qrs in another array. Using Arrays.asList() method - Pass the required array to this method and get a List object and pass it as a parameter to the constructor of the ArrayList class.Ĭollections.addAll() method - Create a new list before using this method and then add array elements using this method to existing list. I have an ArrayList with values like 'abcdxyz' and 'mnopqrs'. To provide the correct type for the array argument, you need to use the specific class or in this case use reflections. We can convert an array to arraylist using following ways. To return an array of a specific type, you need to use toArray (Object ). ![]()
