11 This class provides test input for OneStatementPerLineCheck with different
12 types of multiline statements.
13 A Java statement is the smallest unit that is a complete instruction.
14 Statements must end with a semicolon.
15 Statements generally contain expressions (expressions have a value).
16 One of the simplest is the Assignment Statement.
