there are different type of data types such as int,char
etc.for example suppose if we using arrays it can store a
similar data types but we need to store a char and int in a
same array what can we do for this situation. the wrapper
class helps in this situation by storing a objects in to a
arrays.

example

ArrayList v=new ArrayList();
v.add(new Integer(1));
v.add(new Character('a'));//

the int and char are different type but we stores it by an
object.
