Java basics

Java is high-level, object-oriented, platform independece programming language.

Java was the third most popular programming language in 2022 according to GitHub. Java created by James Gosling at Sun Microsystem. It was released in may 1995 as a core component of Sun's Java platform.

Java follows the object-oriented paradigm, which means it revoves around objects and classes. This approach helps in organizing code in a more manageable and reusable way. 

One of Java's standout feature is its platform independece. Java code is compiled into bytecode, which can run on any system that has a Java Virtual Machine(JVM). This principle is often summed up by the phrase "Write ones, Run Any Where"(WORA)

Java includes strong memory management, exception handling and type checking reliable and bug-free code. It also provides a secure execution environment by running programs inside the jvm. 

As of March 2024 Java 22 is the latest version Java 8,11,17 and 21 are previous LTS versions still officially supported
