Re: what is the concept of Wrapper Classes in java
A primitive data type is not object; in java most of the time objects are used. To use a primitive data type as object we need to wrap it into a its corresponding object class.
A primitive wrapper class in the Java programming language is one of eight classes provided in the java.lang package to provide object methods for the eight primitive types.
Primitive type Wrapper class
byte Byte
short Short
int Integer
long Long
float Float
double Double
char Character
boolean Boolean
These wrapper classes are very important as in many cases we need objects, e,g. many functions do not accept primitive data type as arguments they require objects.
