That feature makes it possible to develop an object-oriented program that has learning capabilities.

In complex object-oriented programs or libraries the highest-level classes may be inheriting from tens of classes.

Frink also allows writing of object-oriented programs, although inheritance is not yet implemented.

Instrumenting overhead can be high for higher-order or object-oriented programs.

Figure 5 illustrates possible join points in the execution of a small object-oriented program.

In computer programming, a trait is a collection of methods, used as a "simple conceptual model for structuring object-oriented programs".

An object-oriented program is described by the interaction of these objects.

MOPs are implemented as object-oriented programs where all objects are metaobjects.

For object-oriented programs, extensive use of polymorphism can be used.

In object-oriented programs, classes are often provided with methods for getting and setting instance variables.
