Key differences between Java and Kotlin

Characteristic	Java	Kotlin
Syntax	Java has a verbose syntax with a lot of boilerplate code, whereas Kotlin has a concise and expressive syntax that reduces the amount of code needed to accomplish the same task.	Kotlin has a concise and expressive syntax that reduces the amount of code needed to accomplish the same task compared to Java.
Paradigm	Java is an object-oriented programming language that supports imperative and declarative programming paradigms, whereas Kotlin is a statically-typed programming language that supports both object-oriented and functional programming paradigms.	Kotlin is a statically-typed programming language that supports both object-oriented and functional programming paradigms.
Typing	Java is a statically-typed language, which means that the type of a variable is determined at compile-time, whereas Kotlin is also a statically-typed language but supports type inference, which means that the type of a variable can be inferred by the compiler.	Kotlin is a statically-typed language that supports type inference, which means that the type of a variable can be inferred by the compiler.
Performance	Java has a reputation for being fast and efficient due to its Just-In-Time (JIT) compiler, which compiles bytecode into machine code at runtime. Kotlin also has good performance, but it is slightly slower than Java due to its additional features.	Kotlin has good performance, but it is slightly slower than Java due to its additional features.
Libraries and frameworks	Java has a vast collection of libraries and frameworks, including Spring, Hibernate, and Struts, which are widely used in enterprise applications. Kotlin can also use these libraries and frameworks, but it also has its own set of libraries and frameworks, such as Ktor and Anko.	Kotlin can use Java's vast collection of libraries and frameworks, but it also has its own set of libraries and frameworks, such as Ktor and Anko.
Community and support	Java has a large and active community with a wealth of resources and support available, including documentation, forums, and tutorials. Kotlin's community is growing rapidly, but it is still smaller than Java's.	Kotlin's community is growing rapidly, but it is still smaller than Java's. However, there are still a wealth of resources and support available, including documentation, forums, and tutorials.
Learning curve	Java has a steep learning curve due to its verbose syntax and complex concepts, such as object-oriented programming and memory management. Kotlin has a much gentler learning curve due to its concise syntax and ease of use.	Kotlin has a much gentler learning curve than Java due to its concise syntax and ease of use.
