D.4.13 Explain the advantages of using library collections.

Library Definition

"In computer science, a library is a collection of non-volatile resources used by computer programs, often to develop software. These may include pre-written code and subroutines, classes, values or type specifications."

The value of a library lies in the reuse of the behavior. When a program invokes a library, it gains the behavior implemented inside that library without having to implement that behavior itself. Libraries encourage the sharing of code in a modular fashion, and ease the distribution of the code.

Advantages Use of Libraries

• use of library provides convenient and reliable implementations of common programming tasks.

• it supports code reuse, thus increases code writing efficiency

• (Programmers can select an appropriate object class from the library and not have to design, implement and test it)

• Encourages code sharing in modular fashion, and ease the distribution of the code
