Difference Between Java And Ruby
Java is a high-level, open-source, object-oriented, and general-purpose programming language. Java is both compiled and interpreted programming language as its source code first compiled into byte code then the byte code is interpreted by JVM. In 1995, it was developed by James Gosling at Sun Microsystems.
Companies using Java are Uber, Airbnb, Google, Netflix, Pinterest, Amazon, etc.
Ruby is a high-level, purely object-oriented, and general-purpose programming language. It is an interpreted programming language. In the mid-1990s, it was developed by Yukihiro “Matz” Matsumoto in Japan.
Companies using Ruby are Github, Shopify, Twitter, Airbnb, Dribbble, etc.
The differences between Java and Ruby are as follows:
|Java is a high-level, open-source, object-oriented, and general-purpose programming language.||Ruby is a high level, purely1990sa fewer, object-oriented, and general-purpose less-load programming language.|
|Java is considered as both compiled and interpreted programming language.||Ruby is an interpreted programming language.|
|In 1995, it was developed by James Gosling at Sun Microsystems.||Ruby was developed by Yukihiro “Matz” Matsumoto in Japan in the mid-1990s.|
|It is a little complex and a general-purpose language but a little slower than Ruby.||It is simpler and little faster than Java.|
|To load a package in Java, import statement is used.||To import a package or a module, require a statement in Ruby is used.|
|Java is a good choice for high traffic sites and huge computational applications.||Ruby is a good choice for fewer high-traffic traffic sites and less load computational applications.|
|Only classes have objects.||Variables, numbers and methods all are objects.|
|It uses static typing.||It uses dynamic typing.|
|As it has static typing, casting is used in Java.||As it has dynamically typed variables, casting is not used.|
|Parentheses are mandatory in Java.||Parentheses are not mandatory in Ruby.|
|To define a method/class block in Java braces are used.||To define a method/class block in Ruby ‘end’ keyword used.|
|It is having package access by default and can be declared with identifiers.||All the member variables are private.|
|In Java class definitions have an access modifier.||While in Ruby class definitions do not have an access modifier like Java.|
|Web app frameworks are Spring, JSF, GWT etc.||Web app frameworks are Ruby on Rails, Sinatra, Hanami, etc.|
|Null value is declared with “null”.||Null value is declared with “nil” keyword.|
|Companies using Java are Uber, Airbnb, Google, Netflix, Pinterest, Amazon etc.||Companies using Ruby are Github, Shopify, Twitter, Airbnb, Dribble, etc.|
