The JRE is the Java Runtime Environment, it covers most end-users needs. Contains everything required to run Java applications on your system. It is a package of everything necessary to run a compiled Java program, including the Java Virtual Machine (JVM), the Java Class Library, the java command, and other infrastructure. However, it cannot be used to create new programs. The JDK is the Java Development Kit, the full-featured SDK for Java. It has everything the JRE has, but also the compiler (javac) and tools (like javadoc and jdb). It is capable of creating and compiling programs. Usually, if you only care about running Java programs on computer you will only install the JRE. On the other hand, if you are planning to do some Java programming, you need to install the JDK instead. Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server.
