Regarding type casting

[Vijay Chandran]

Dear friends,

Please help me in this type casting problem:

I am using JDK 1.4.
I want to convert a long(primitive data type) type cast it and assign it to a Long(Wrapper class) variable.

Kindly provide your help regarding this pronlem.
Thanks in advance.

Regards,
Vijay

Use Long.valueOf(long)

Note that this is not type-casting. You are constructing a new object.

Type casting is for object references or primitives.

For object references, you type cast when you have declared a reference as a superclass, but you know that the object it points to is actually of some subclass.

For primitives, you type cast when you want to force the primitive value into a variable whose type is not automatically compatible. For instance, you can assign an int value to a long, with no cast. But if you want to assign a long to an int, you need to cast. If the long does not fit in the int, information will be lost.
