many of you know about java array but here I am going to post about java arraylist.
First what is the Arraylist ? we will see
ArrayList is used for storing Object/data in each index of arraylist .It is similar to array but Array is used for storing single data in each index of array.
Mainly few instance methods/funtions are using here
1.find the size of arraylist
2.adding object a given index
3.remove object that we want
and so on.
