Some of the good scenarios where Composite design pattern can be

used are as follows:

Tree Structure: The most common use of Composite design pattern

is Tree structure. If you want to represent data in a Tree data

structure, Composite pattern can be used.

E.g. In an Organization, to a Manager has Employees. But Manager

is also an Employee. If we start from CEO level, there is one big

tree for the whole organization structure. Under that big tree there

are many sub-trees. This can be easily represented with Composite

design pattern.

Recursion: Another use of Composite design pattern is Recursion. If

we have a Recursion based algorithm, we need data to be passed to

algorithm in a data structure that treats individual objects and

compositions at each level of recursion uniformly.

E.g. To implement a recursive Polynomial Solving algorithm, we

can use Composite design pattern to store the intermediate results.

Graphics: Another good use of Composite design pattern is in

Graphics. We can group shapes inside a composite and make

higher-level groups of smaller groups of shapes to complete the

graphics to be displayed on screen
