Inheritance is a means where a class borrows ("inherits") functionality from a base class, usually as a means of code reuse; the subclass will often add additional functionality or modify the behavior of the base class. Packages are simply a way of organizing code into namespaces, such that: Only classes that are actually part of the application logic are included, to prevent conflicts from classes that have the same name, and to logically organize code so that similar functionality can be grouped together.
The 'is a' relationship is expressed with inheritance and 'has a' relationship is expressed with composition. Both inheritance and composition allow you to place sub-objects inside your new class. Two of the main techniques for code reuse are class inheritance and object composition. Inheritance [ is a ] Vs Composition [ has a ] Building Bathroom House class Building{ ....... } class House extends Building{ ......... } is a [House is a Building] class House { Bathroom room = new Bathroom() ; .... public void getTotMirrors(){ room.getNoMirrors(); .... } } is a has a [House has a Bathroom] has a Inheritance is uni-directional. For example House is a Building. But Building is not a House. Inheritance uses extends key word. Composition: is used when House has a Bathroom. It is incorrect to say House is a Java - Fundamentals 19 Bathroom. Composition simply means using instance variables that refer to other objects. The class House will have an instance variable, which refers to a Bathroom object.

One key difference is that autosomal traits are located on the autosomes (non-sex chromosomes), while sex-linked traits are located on the sex chromosomes (X or Y). This difference affects how these traits are inherited and expressed, as sex-linked traits show different inheritance patterns among males and females.
