Can you explain what is meant by build time in software development?

Build time is a stage in the software development process when source code is transformed into an executable file or package. During this stage, the compiler or build system performs the following tasks:

• Compilation of source code into machine code or bytecode.
• Linking of various modules and libraries.
• Code optimization.
• Generation of artifacts (e.g., JAR files in Java).

In Java, for example, build time includes compiling .java files into .class files using javac. This stage occurs before the program runs and is different from runtime, when the program is already executing.

Thus, build time is a preparatory stage necessary for creating an executable application from source code.
