This promotes code reusability and establishes a hierarchical relationship between classes. Key Concepts Superclass (Parent Cla...
All Classes in the Java Platform are Descendants of Object At the top of the hierarchy, Object is the most general of all classes. Classes near the bottom of the hierarchy provide more specialized behavior. An Example of Inheritance Here is the sample code for a possible implementation of a ...
multiple code inheritance problem.; We describe the implementation of MCI-Java, an extension to Sun's Java 1.2.2 that separates code-types and data-types and thereby enables a multiple code inheritance mechanism. IBM's Jikes Compiler 1.15 is modified to provide compiler support for MCI-Java. ...
