Special note: The Java language does not allow a local variable declaration
to appear as the "then" part of an if statement (they may only appear within a
block). However, the AST will allow a VariableDeclarationStatement
as the thenStatement of a IfStatement. To get something that will
compile, be sure to embed the VariableDeclarationStatement
inside a Block.

this if statement has no "else" part.
Note that there is a subtle difference between having no else statement and having an empty statement ("{}") or null statement (";").

Note that there is a subtle difference between having no else part
