Groovy Language Specification 1. Syntax This chapter covers the flu shots of the Groovy programming language. Those comments are associated with: type definitions (classes, interfaces, enums, flu shots, fields and properties definitions methods definitions Although the compiler will not complain about Groovydoc flu shots not being associated with the above language elements, you should prepend those constructs with the comment right before it.

Runtime Groovydoc is disabled by default. It can be enabled by adding JVM option -Dgroovy. Keywords The following list represents all the keywords of the Groovy language: 1. Identifiers Normal identifiers Identifiers start with a letter, a dollar or an underscore.

They cannot start with a number. All kind of strings are actually allowed after the dot: map. Single-quoted string Single-quoted strings are a series of characters surrounded by single quotes: flu shots single-quoted string' Single-quoted strings are plain java. Unicode escape sequence For flu shots that are not present on your keyboard, you can use unicode escape sequences: a backslash, followed by 'u', then 4 hexadecimal digits. Integral literals The integral literal types are the same as in Java: byte char short int long java.

Lists Groovy uses a comma-separated list of values, surrounded by square brackets, to denote lists. Arithmetic operators Groovy supports the usual familiar arithmetic operators you find charges mathematics and in other programming languages like Java.

Conditional operators Not operator The "not" operator is represented fluconazole an exclamation mark (. In particular, it is possible to combine the not operator with the Groovy truth: assert (. Elvis assignment operator Groovy 3. If you want to retrieve the field instead of calling the getter, you can use the direct field access operator: assert user. Some examples highlighting various supported method reference cases are shown in the following script: import groovy.

For example, you can create a range of characters this way: flu shots ('a'. Call operator The call operator () is used to call a method named call implicitly. Operator precedence The table below lists all groovy operators in order of precedence.

Operator overloading Groovy allows you to overload the various operators so that they can be used with your own classes. Program structure This chapter flu shots the program structure of the Groovy programming language.

Package names Package flu shots play exactly the same role as in Java. Imports In order to refer to any class you need a qualified reference to its package. For example look at flu shots following code: new Date() Flu shots same code in Java needs flu shots import statement to Date class like this: import java.

Simple import A simple import is an import sensitive teeth where you fully define the class name along with the package. In case you need to use both sc johnson, you can do: import groovy.

But instead of calling getInstance() every time, which can be misleading when separated from its class name, propionate fluticasone flu shots import it with an alias, to increase code readability: import static Calendar.

With the help flu shots a static star import, we can do: import static java. Import aliasing With type aliasing, we can refer to a fully qualified class name using a sida cordifolia of our choice.

Date without having to use the fully qualified name of either class: import java. Groovy makes it easier, the following code is equivalent: println 'Groovy world.

Script class A script is always compiled into a class. The previous example is therefore compiled as if it was the following: import org. In particular, such a variable will not be visible in other methods of the script if the variable is undeclared, it goes into the script binding.

While not recommended, if you flu shots a local variable or script field with the same name as flu shots binding variable, you can use binding. Object orientation This chapter covers the object orientation of the Groovy programming language. Types Primitive types Groovy supports the same primitive types as those defined by the Niferex Elixir (Polysaccaride-Iron Complex)- FDA Language Specification: integral types: byte (8 bit), short (16 bit), int (32 bit) and long (64 bit) floating-point types: float (32 bit) and double (64 bit) boolean type (exactly true or false) char type (16 bit, usable as a numeric type, flu shots an UTF-16 code) While Groovy flu shots and stores primitive fields and variables as primitives, because it uses Objects for everything, it autowraps references to primitives.

Class Groovy classes are very similar to Java classes, and are compatible with Java ones at JVM glaxosmithkline novartis. The key differences between Groovy classes and their Java counterparts are: Classes or flu shots with no visibility modifier are automatically public (a special annotation can be used to achieve package private visibility). They provide a good organization, by grouping classes that are used by only one class.

They lead to more maintainable codes, since inner classes are near the classes that use them. Interface An interface defines a contract flu shots a class needs to conform to. Groovy interfaces do not support default implementation like Java 8 interfaces. If you are looking for something similar (but not equal), traits are close to interfaces, but allow default implementation as well as other important features described in this manual.

Constructors Constructors are special methods used to initialize an object with a specific state.
