Java is a multi-platform, object-oriented, network-centric, programming language developed by Sun Microsystems. Java is a programming language and a computing platform for application development. It was first released by Sun Microsystem in 1995 and later acquired by Oracle Corporation
In this tutorial, you will learn:
Here are the important features of Java.
Here are important features of scala:
Here are the main difference between Java and Scala.
|Compactness||More compact and concise||Comparatively larger chunks of code|
|Designed for||It is designed and developed to be both object and functional oriented language. It supports a wide variety of functional programming features such as concurrency and Immutability.||Originally developed as an object-oriented language and started supporting functional programming features in recent days. It is not as strong as a functional programming language.|
|Concurrency model||Uses actor model for supporting modern concurrency||It uses the conventional thread-based model for concurrency.|
|Supported frameworks||Supports frameworks – Play, Lift||Supports Spring, Grails, much more|
|Lazy evaluation support||Supports lazy evaluation||Does not support lazy evaluation|
|Static members||No static members||Contains static members|
|Operator overloading||Supports operator overloading||Does not support operator overloading|
|Compilation process||Compilation of source code is comparatively slow||Compilation of source code is faster than Scala|
|Interfaces||Traits – act like Java 8 interfaces||Java 8 interfaces try to bridge the gap between classes and interfaces|
|URL rewriting||Rewriting is needed||Rewriting is not required|
|Bug-free codes||No assurance about the bug-free codes||Complete assurance of lesser defects|
|Support for backward compatibility||Scala does not support backward compatibility||Java supports backward compatibility|
|Support for Multiple inheritances||Supports multiple inheritances using classes but not by abstract classes||Does not support multiple inheritances using classes, but by interfaces|
|Code style||Code is written in a compact form.||Code is written in long-form.|
|Static keyword||Scala does not contain the static keyword.||Java contains the static keyword.|
|Treats||Any method or function present in Scala is they are treated like they are variable.||Java treats functions as an object.|
|Type of variables||Scala variables are by default immutable type.||Java variables are by default mutable type.|
|Object orientation||Scala treats everything as an instance of the class and it is more object-oriented language as compare to Java.||Java does not support operator overloading.|
|Calling method||In Scala, all the operations on entities performed using method calls.||Operators are treated differently and is not done using the call method.|
|Readability||Scala is less readable because of its nested code.||Java is more readable.|
|Compiling process||Compiling the process of source code into byte code is very slow.||Compiling the process of source code into byte code is fast.|
