Answer / mohammad fazulullah

Array is the object and it stores the object of same type

Eg : Its stores complete integer types or string types

Arraylist is the collection in which we can store the
objects of any data type.

Eg : Arraylist Arr = new Arraylist()
Arr.Add(13); // Integer Type
Arr.Add(10); // String Type

Answer / ranganathkini

A java.util.ArrayList has the following characteristics over
an array:

1. Provides a resizable array implementation
2. Implements the java.util.List interface
3. Has a tuning parameter called initialCapacity which
specifies the number of elements the ArrayList can hold
before it has to be resized.

Difference between array and arraylist...

Answer / vibhor

An ArrayList is resizable, where as, an array is not.
ArrayList is a part of the Collection Framework. We can
store any type of objects, and we can deal with only
objects. It is growable. Array is collection of similar
data items. We can have array of primitives or objects. It
is of fixed size. We can have multi dimensional arrays.
Array: can store primitive ArrayList: Stores object only
Array: fix size ArrayList: resizable
Array: can have multi dimensional
Array: lang ArrayList: Collection

Difference between array and arraylist...

Answer / pooja

ARRAY:
array is a userdefined datatype in almost all languages.
array is able to store only one type of values.
syntax:array a1[10];in c
array a1=new array[10];in c++ &java
that means array can store fixed no of values,ofcourse we
can dynamically allocate memory in java but we can't extend
the size.
ARRAYLIST:
arraylist is not supported in c
it is also a type of array in which we can extend size
dynamically.
syntax:
ArrayList ar=new ArrayList();
where ArrayList is a class
