Boilerplate is the term used to describe sections of code that have to be included in many places with little or no alteration. It is more often used when referring to languages which are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs. Boilerplate Code means a piece of code which can be used over and over again or we can say it, a piece of reusable code.
