Key differences between Ruby and Java

CharacteristicRubyJava
SyntaxRuby has a more concise and flexible syntax compared to Java.Java has a more verbose and rigid syntax compared to Ruby.
ParadigmRuby is a dynamically-typed, object-oriented language that also supports functional programming.Java is a statically-typed, object-oriented language that does not support functional programming out of the box.
TypingRuby is dynamically-typed, meaning that variable types are determined at runtime.Java is statically-typed, meaning that variable types are determined at compile-time.
PerformanceRuby is generally slower than Java due to its interpreted nature and dynamic typing.Java is generally faster than Ruby due to its compiled nature and static typing.
Libraries and frameworksRuby has a strong focus on developer productivity and has a large number of libraries and frameworks available, such as Ruby on Rails.Java has a large number of libraries and frameworks available, but can be more complex to use and configure compared to Ruby.
Community and supportRuby has a strong and active community, with many resources available for learning and support.Java also has a strong and active community, with many resources available for learning and support.
Learning curveRuby has a relatively low learning curve due to its concise syntax and focus on developer productivity.Java has a steeper learning curve compared to Ruby due to its verbose syntax and complex configuration.
