Apache Groovy

Apache groovy considered being an object oriented programming language. This is used for the java platform. It is static as well as dynamic language. This Groovy has characteristics similar to python, Ruby, perl and smalltalk. This groovy will be used for programming language and scripting language for the java platform.

Groovy is having many features like DSL support, closures and also dynamic typing. Like all other programming language, groovy cannot replacement for java. The source code of groovy will not be a replacement for java. The source code of groovy complies in java Bytecode, so that will be run on any platform where JRE is installed.

Why Apache Groovy is used for?

Apache groovy, is robust typed and dynamic language, with static-typing and static compilation capabilities java platforms has goal at improving developer productivity. It combines smoothly with any java program and in no time delivers to our application powerful features, including scripting capabilities.

  1. Flat learning curve-it is concise readable and expressive syntax and also easy to learn for java developers.
  2. It has good integration with Java- Integrates and interoperates well with java and any third party libraries.
  3. It is vibrant and very rich ecosystem-webdevelopment, reactive applications, concurrency/asynchronous/parallelism library, test framework build tools, code analysis GUI building.
  4. Powerful features-There are closures,constructors, runtime and compile time meta programming and  and also functional programming languages exists.
  5. Domain specific language-
  6. Scripting and testing glue-There is a writing maintainable tests all entire our build and automation tasks.

A range can be a shorthand for mainly telling a sequence of values.A range is denoted by the first and last values in sequence and Range will be inclusive or may be exclusive.A inclusive range will include all the values from the first to the last while an exclusive range includes all the values except the last.There are some examples of range literals

1…10-An example of an inclusive range

1….<10-An example of an exclusive range

‘a’….’x’-Ranges that can consists of characters

10….1-Ranges can also be in a descending order.

There are many methods

1. Contains- It will check if a range has specific values.

2. Get

It returns the element at the specified position in this range.


It get the lower value of range


It will get the upper value of this range

5. isReverse

Is this a reverse range iterating backwards.


Returns the number of elements in this range.


Returns a view of the portion of this range between the specified fromindex inclusive,andtolindex,exclusive.


Traits are the structural construct of the language that will allow

the composition of behaviors

Runtime implementation of interfaces

Compatibility with static type checking/compilation
