Key differences between Kotlin and Java

Characteristic	Kotlin	Java
Syntax	Kotlin has a more concise and expressive syntax compared to Java. It supports features like null safety, extension functions, and operator overloading.	Java has a more verbose syntax compared to Kotlin. It does not support null safety, extension functions, or operator overloading.
Paradigm	Kotlin is a multi-paradigm language that supports both object-oriented and functional programming.	Java is an object-oriented language that supports some functional programming concepts through the use of lambda expressions.
Typing	Kotlin is a statically typed language that supports type inference.	Java is a statically typed language that does not support type inference.
Performance	Kotlin has similar performance to Java as it compiles to bytecode that runs on the Java Virtual Machine (JVM).	Java has good performance due to its efficient bytecode and just-in-time (JIT) compilation.
Libraries and frameworks	Kotlin has good interoperability with Java libraries and frameworks. It also has its own set of libraries and frameworks like Ktor and kotlinx.	Java has a vast ecosystem of libraries and frameworks like Spring, Hibernate, and Apache Struts.
Community and support	Kotlin has a growing community and is backed by JetBrains, the company behind popular IDEs like IntelliJ IDEA and Android Studio.	Java has a large and mature community with extensive documentation and support.
Learning curve	Kotlin has a relatively low learning curve for Java developers as it is interoperable with Java and has a similar syntax. It also has good documentation and resources.	Java has a moderate learning curve for beginners due to its verbose syntax and concepts like object-oriented programming and memory management.
