A computer programming language is said to adhere to the off-side rule if in it the scope of declarations is expressed by their indentation, i.e., blocks are formed via indentation.... ). Unlike paragraphs, statement blocks can be nested; that is, with one block inside another. Blocks often define the scope

In computer programming, scope is an enclosing context where values and expressions are associated. Various programming languages have various types of scopes.... of the identifiers used within.
Blocks become more independent when they can have their own variables, i.e. if identifiers defined inside a block cannot be referred to from outside that block. Languages without lexical scoping such as Javascript

Java programmers typically use a slightly different convention for placing the braces. The opening brace is on the same line as the method
Method (computer science)
In object-oriented programming, a method is a subroutine that is exclusively associated either with a class or with an object . Like a procedure in procedural programming languages, a method usually consists of a sequence of statement to perform an action, a set of input parameter to customize those actions, and possibly an output value... declaration:

Visual Basic requires an explicit End statement, as follows:
