Answer / mohammad fazulullah
Array is the object and it stores the object of same type
Eg : Its stores complete integer types or string types
int[] IntArray = new int[3];
string[] StringArray = new StringArray[2];
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
2 . Arrays has the Fixed Lenght where as the Arraylist
varies the leghth as the objects Added.

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.

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

Answer / karunakar
Array is the collection of values of the same data type
>the variables in an array is called array elements
>Array is a reference type data type
>The array structure in System's Memory
Array list is a class .
when you want to access the elements of an array through its
index value location in an array,use an ArrayList.
The use of the arraylist is an alternative to the use of th
array.
The Methods Of ArrayList class are
1)Add
2)Remove
3)Clear
4)Insert
5)TrimToSize

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
