Answer 1

Array is a fixed length data structure whereas ArrayList is a variable length Collection class. We cannot change length of array once created in Java but ArrayList can be changed. We cannot store primitives in ArrayList, it can only store objects. But array can contain both primitives and objects in Java

Answer 2

variable stores one value;
array or list can store more values of the same type and usually same purposes, eg list of students, list of books, words, characters, numbers. then you can fast address the value, change it, and easy iterate all vales.
