A library in programming code is a collection of similar objects that are stored for occasional use. It is a collection of reusable and precompiled programming routines that the programmer can "call" when writing code so that the programmer can just use and not have to write it. Frameworks are reusable software environments that provide functionality to facilitate development of software applications, products and solutions. They can include compilers, code libraries, tool sets and application program interfaces to help the development of projects and solutions. A namespace are structured hierarchies that serve to allow the reuse of different names in different contexts, and have a purpose of avoiding name collisions between multiple identifiers that share the same name. A class is like a blueprint, it is basically set of instructions that define how an object looks and its specifications, they can store things and do things.
