What is compile?
Compiling
is the process of taking source code written in a programming language, such as Java, and converting it into a format that can be read and executed by a computer. The compiled code is usually referred to as an executable, which is a file that contains a set of instructions that can be run by a computer. Compiling source code is a crucial step in the development of any software program or application. Compiling source code allows developers to create efficient and reliable programs that are optimized for specific hardware and operating systems. Additionally, compiling source code allows for faster execution of the program, since the computer does not need to interpret the source code each time the program is run. Furthermore, compiling source code can make it easier to debug and improve the code, since errors are easier to catch in the compiled form.
