    Java provide equivalent class types for primitive types.

    int - Integer
    double - Double etc...

    These classes are called wrapper classes, because they are wrapping the primitive values.
    Before java 1.5 to wrap a primitive value there are workarounds.

    From java 1.5 it is automated. That is why this is called autoboxing.
    from java 1.5 we can write

    Integer i=10;
    Double d=10.5;

    you don't need to write any object creation code
    Eg. Double d=new double();
