Everything was well organized. I would like to refer to some of their courses to my peers as well. The customer support was very interactive. As a small suggestion to the trainer, it will be better if we have discussions in the end like Q&A sessions.

Groovy FAQs

Groovy

Groovy is an object-oriented programming language used as JAVAscript. It is a compatible, compiled to Java virtual machine (JVM),with features similar to that of Python, Ruby and Smalltalk . The language can be used to combine Java modules, extend existing Java applications and write new ones. Groovy uses all Java classes and libraries and builds nicely on Java’s strengths, which allows for more efficient coding. Groovy script is fully parsed, compiled, and generated before executing the data. Groovy source code gets compiled in Java Bytecode so it can be run on any platform if an application is installed on that operating system. It has an agile and dynamic performance.

Groovy is basically used for scripting for java and is used for the following: 

  • Simplicity:Build on top of Java standard libraries, providing extra features. Most of them make programming much instant, simpler and convenient.
  • String interpolation: evaluation of a string function is done thoroughly. Here, placeholders are surrounded by${}or prefixed with $ for dotted expressions.
  • Type Casting:With as operator Groovy makes casting very readable and clear. To use this operand the casted class must implement the asType() method.
  • Power Assertions: It offers the same assert statement as that of Java, but is way more powerful. In case the assertions fails the output resolves to false.
  • Defining variables: Groovy offers incredible flexibility. One can define a variable with its type or simply use the keyword def especially when declaring lists or maps.
  • Operators: operators allowed here are Elvis operator(ternary operator), Safe navigation operator(variable check) and Spread Operator(iteration).

Groovy is a multi-faceted open-source general purpose programming language for the Java platform.  It supports an easily understandable and publicly accessible source code that anyone can inspect, modify, and enhance unlike some software which has source code that only the person, team, or organization who created it and maintains exclusive control over it can modify  While primarily an object-oriented language with many dynamic language features, it also supports functional programming, static and dynamic type checking and compilation.Programmers who would like to view that code, copy it, learn from it, alter it, or share it can do it with zero hindrance.

Groovy is an accomplished object-oriented (OO) language that supports all of the OO programming concepts that are familiar to Java developers such as classes, objects, interfaces, inheritance, polymorphism, and others. Groovy compiler will not convert such scripts into Java classes of type groovy.lang.Script though. A class in Groovy declares the state (data) and the behavior of objects defined by that class. Hence, a Groovy class describes both the instance fields and methods for that class. Together, the data and methods of a class are used to represent some real world object from the problem domain. These objects can be accessed, modified, moved and combined with other objects as well.

Groovy offers stylised type casting. It is vastly used for developing apps and games. Groovy can be used as a programming language as well as a scripting language for the Java Platform and is compiled to Java virtual machine (JVM) bytecode which operates seamlessly with other Java code and libraries. Groovy uses a curly-bracket syntax similar to Java's. It is statically typed languages are those in which type checking is done at the compiling stage and not during execution. Java is a general purpose statically typed language. One can easily simply write the codes without any interruption.

Both JAVA and Groovy are in huge competition in the market today.

GROOVY

  • It has a strong, static and dynamic typing discipline and are saved with typical ``.groovy” file extension.
  • It is Compiled with JVM byte code and is compatible with JAVA platform.
  • On Groovy things are by default publici.e., a method without any access modifier is public and accessible outside of class and package boundaries.
  • Syntax is quite similar to that of JAVA.
  • For class members in Groovy, getters and setters are generated automatically.
  • Since Groovy is a Scripting language, there's automatically a wrapping class called Script for every program.

JAVA

  • Java is a static, safe and strongly typed programming language with file extension names “.java” or “.class”.
  • It is developed on JDK and run on JVM.
  • It has a strong disciple syntax.
  • If access modifier is not specified, it becomes a private package.
  • In Java, you need to provide getters and setters method for fields, especially if you are following JavaBeans naming convention and use tools and libraries, which uses reflection to dynamically access and mutate bean properties.
  • In Java, one needs a main method to make a class executable.

Groovy has a Dynamic Performance.Groovy scripts can be statically compiled providing near Java code performance. Groovy syntax is concise, instant, simple and easy. It saves a lot of code and effort thus increasing the productivity of developer if he had to do the same thing in Java. It has instant implementation  of code it allows polymorphism where when a parent class reference is used to refer to a child class object. Here, callback patterns are made easy to implement. Compilation is done during runtime. The syntax has an understandable and readable format.

The syntax and the codes written in groovy are simple and accessible. One can write Groovy code online and just execute it to quickly play around with some snippets. No huge complicated programs are required. If one is familiar with c or other basic programming languages. Since it has a code structure similar to that of Python, JAVA, having knowledge of only one of these makes it quite easier for the user. Only the basic programming codes are required. After installation, Groovy is ready to work with.Groovy deals primarily with classes and objects. A class in Groovy is declared by the state (data) and the behavior of objects is defined by that class. Both the instance fields and methods for the class are described by Groovy class. These objects can be accessed, modified, moved and combined with other objects as well.

Today, developers look for something which is agile and takes no time. Its efficiency has pushed the mass to go wild. Being user-interactive, new features are updated instantly. Its concise and direct syntax permits developers that use Groovy to develop projects in a simplified manner. It has been ranked among the Top 20 in the Tiobe Index of language popularity after a two-year absence. Groovy had been at No. 49 a year ago. Because of its use in writing scripts for the popular JENKINS CI/CD, Groovy is expected to maintain its rank, which provides effective software quality services. these rankings are based on a formula that assesses searches on languages in popular search engines such as Google, Bing, Yahoo, and Wikipedia. Groovy also uses a domain specific language is a programming language or a specification dedicated to solving specific problems, through a specific technique. Because of these features its suffering a rapid growth in the technological industry.

Groovy Grails

Grails is also an open source web application framework that performs on Groovy programming. Like Groovy, this application also permits the product accessibility publicly. For now in this tech startup it has been a silent contributor. The following features make it more interesting:

  • Robust framework: Groovy being a user interface software needed a more efficient framework while coding. Grail’s amazing framework makes it more significant, concise and well organised.
  • Power of JAVA: Groovy on Grails gets well with the Java. The framework seamlessly and transparently integrates and collaborates with Java, the JVM, and existing Java EE containers giving the Java developers truckload of advantage.
  • Excellent for startups: Unlike other Java web toolkits, the Groovy on Grails does not ask to assemble development units which can be tedious. Instead the Grails provides a development environment that includes a web server to get developers started right away. All required libraries are part of the Grails distribution and prepares for its formation automatically.
