Question

Is there a more elegant solution to convert an ‘Arraylist‘ into a ‘Arraylist<Type>‘?

Current code:

ArrayList productsArrayList=getProductsList();
ArrayList<ProductListBean> productList = new ArrayList<ProductListBean>();

for (Object item : productsArrayList)
{
  ProductListBean product = (ProductListBean)item;
  productList.add(product);
}

Answer 1

ArrayList<ProductListBean> productList = (ArrayList<ProductListBean>)getProductsList();

Note that this is inherently unsafe, so it should only be used if getProductsList can’t be updated.
