A package declaration appears within a compilation unit to indicate the package to which the compilation unit belongs.

Instances
data ImportDecl Source #
An import declaration allows a static member or a named type to be referred to by a single unqualified identifier. The first argument signals whether the declaration only imports static members. The last argument signals whether the declaration brings all names in the named type or package, or only brings a single name into scope.
Constructors

A class declaration specifies a new named reference type.

There are two kinds of types in the Java programming language: primitive types and reference types.
There are three kinds of reference types: class types, interface types, and array types. Reference types may be parameterized with type arguments. Type variables cannot be syntactically distinguished from class type identifiers, and are thus represented uniformly as single ident class types.

A class or interface type consists of a type declaration specifier, optionally followed by type arguments (in which case it is a parameterized type).

A primitive type is predefined by the Java programming language and named by its reserved keyword.
A class is generic if it declares one or more type variables. These type variables are known as the type parameters of the class.
A single identifier.
