Like the base model car, JRE enables the ability to create Java Applications for different types of deployments using minimal core tools to accomplish the task. There are two standard types of installations, JRE (Java Runtime Environment) and JDK (Java Development Kit). Well, that’s the same concept when we take a closer look at Java. If you had the option to choose between a base model car or a fully loaded model, which one would you choose?īoth cars will take you from point A to point B, but with the fully loaded car you have additional features that can make rush hour a chill hour. ![]()
