wrapper classes allow primitive data types to be accessed
as objects.Once assigned a value the value of wrapper
classes can't be changed.

Answer / ravikiran

wreapper classes will allow the primitive types to act like
objects

Answer / irshad ahmad

Wrapper classes are classes that are used to make primitive
data types into objects, and to make wrapped objects into
primitives because

As we know that vector in java can hold only object; but
can't directly store primitive data types, like int,float,
char, long, double. therefore we need to convert simple data
type to object. This can we done using wrapper classes.

Answer / bhupendra vijay

Wrapper classes are those classes that allow primitive data
types as objects.

Answer / guest

The wrapper classes can take constructors of either the
type they are designed to wrap or of a String that can be
converted to that type. Thus the Integer class can take a
number that could be contained by an int, but an error will
occur if you try to pass a number with a floating point
component. Remember that the wrapper classes are just that
classes, they are not primitives and instances of the
wrappers can only be manipulated in the same way as any
class. You may get questions on the exam with code that
uses standard math operations to manipulate instances of
wrappers. You can of course use the + operator where it
would implicitly call the toString method, but as soon as
you see the - * or % operator, beware.

Answer / adeel

wrapper classes are those who wrapped the primitives one for
sprcific purposes.

Answer / priyanka

When we need to store primitive datatypes as objects, we use
wrapper classes.MEans in utility classes all the utility
classes stores Objects.So when we need to store a primitive
datatype.We make an object of theat primitive data and store it.
Thats why we use Wrapper classes in Java.

int is a primitive data type , where as Integer is a class
which encapsulates the primitive int data type and
represents in terms of object.

Answer / prabhu.poddar

Wrapper class is a representation of the base class for a
set of data source. The java wrapper class dont comparises
the consractor all of the primitive wrapper class in java
are immetable.wrapper class in offers library intilazation
services as well as the access for to the data source
servicess that the wrapper class suports.
