What Are the Main Differences Between Arrays And Arraylists in Java ?

Here are main differences that you need to know when it comes to Arrays and ArrayLists in the Java programming language :

1. While arraylist is implemented as a dynamic sized array, an array is implemented as a basic fixed sized array..

2. To determine the length of an array, use the length variable; however, the size() function is used to determine the size of an ArrayList.

3. While ArrayList uses add() function to insert entries, Array uses basic assignment operator to store elements

4. Inside an array whe can have similar type of data whereas inside an arraylist we can have different type of elements and objects.
