Expression body
Keywords: expression
An expression body can be defined as part of a class expression, but also as in line expression. The expression body is enclosed in brackets '{}' in any case. Expression code may contain some optional parts for defining variables and initializing the expression as well as an error and a final block. The only mandatory part of the expression body is the process code.
