In every class or method, there will be a calling function and a called function.

When ever a function(calling function) calls another function(called function), the called function is expected to reply by executing its method.

Design by contract is such a technique by which an well mannered and defined interface can be developed between the calling and called functions.7

In this manner, the developer will have an excellent chance of understanding the function(method) and the functions pre and post conditions and also it provides documentation to the caller(calling function).

Java uses the assertion construct(assert statement) to implement pre and post conditions.Design by contract is also called as programming by contract and is also supported by exception handling in Java.
