First, notice thatArrayListis a generic class, so you can parameterize it with any type you want and the compiler will ensure that, for example, you will not be able to putIntegervalues inside a collection ofStrings. Also, you don’t need to cast elements when retrieving them from a coll...
on this scenario the arrayList class provides both read and write access for the functions, and also it follows some sequential order for to insert the values on the memory the values are stored as the separate index with the help of indexes the values are retrieved from back end to ...
