JRE

The Java Runtime Environment (JRE) is a software package that lets your computer run Java applications. It includes the Java Virtual Machine (JVM), which interprets Java code into instructions your computer can understand, along with essential libraries and tools needed to execute Java programs. Think of the JRE as a complete environment that ensures Java applications operate smoothly without needing to know all the details of how they work internally. It doesn't include development tools like compilers, so you only need the JRE to run existing Java programs, not to create or edit them.
