Spring Boot is a so called framework („superstructure“) of two related programming languages – Java and Kotlin.These languages were named after two islands – Java in Indonesia and Kotlin near St. Petersburg.Developed by Sun Microsystems (later taken over by the database giant Oracle), Java is one of the oldest widely used programming languages.
Java is used in software development for mid and large enterprises.
Kotlin is Java’s younger, more efficient sibling. Both languages are compiled into so called “bytecode, so ultimately they run in the same environment.
Since 2017, the Kotlin programming language has been Google’s preferred language for Android app developers. Most of the top apps are written in Kotlin, Google itself has its apps written in Kotlin, including Maps and Drive.
Spring Boot enables fast, efficient programming in the environment of these two powerful languages. As a framework – in the right hands – it provides the guarantee of the “cleanly written” code using best programming practices.
