In computer science, an object type (a.k.a. wrapping object) is a datatype that is used in object-oriented programming to wrap a non-object type to make it look like an object.
Some object-oriented programming languages make a distinction between objects and non-objects, often referred to as primitive types for reasons such as runtime efficiency and syntax or semantic issues. For example, Java has object types corresponding to each primitive type: Integer and int, Character and char, Float and float, etc. Languages like C++ make little or no distinction between objects and non-objects; thus, the use of object type is of little interest.
