Programming Languages
We need to understand the terms language and program before moving on to programming languages. Let’s discuss them now.
Language Execution Models
The program development and execution model explains how a program is written, converted, and executed on a system.
What is JDK?
JDK (Java Development Kit) is a complete toolkit used to develop, compile, and run Java applications.
History
Java was developed by James Gosling at Sun Microsystems in the early 1990s as part of the Green Project, initially targeting embedded systems such as set-top boxes and appliances. Originally named Oak (after a tree outside Gosling’s office), it was later renamed Java because the name Oak was already trademarked and Java sounded more unique and appealing.
