No, the JDK includes the JRE.
The JRE refers to Java Runtime Environment... JRE is an implementation of the Java Virtual Machine which actually executes Java programs. Without the JRE we cannot execute our Java programs.
An IDE cannot be part of a JRE. The "JRE" is the Java Runtime Environment. I.e., the JRE is an implementation of the Java Virtual Machine which actually executes Java programs. An IDE refers to - Integrated Development Environment, using which we can develop Java programs and applications. an IDE comes with an implementation of a JRE. so it cannot be part of a JRE
From the command line: sudo apt-get install sun-java6-jre
The JRE refers to Java Runtime Environment... JRE is an implementation of the Java Virtual Machine which actually executes Java programs. Without the JRE we cannot execute our Java programs.
Supported minimum size
On a Windows platform the online Java Runtime Environment (JRE) installer is approximately 0.86 MB and the installed size on disk is about 98MB. The downloadable full Windows offline JRE installer is larger ~30.2 MB and for MacOS ~50 MB.
Minimum size is 36
JRE stands for Java Runtime Environment. JRE is the runtime set up that is required by the JVM to execute java programs. The JRE and JVM (Java Virtual Machine) come packaged along with the Java Development Kit (JDK) that we download and install from the suns website to install Java.
WAS 6.0 runs on JRE 1.4 WAS 6.1 runs on JRE 5
The JVM is part of the JRE (Java Runtime Environment) or the JDK (Java Developer Kit). Both the JDK and JRE are packages available from a variety of sources. The most common one is available from Sun (now Oracle). You simply visit the web site, and it will then download and install the JRE for you after you answer a couple of questions: http://www.java.com/
First of all, JDK is Java Development Kit and JRE is java runtime Environment. JDK provides compiler and all the necessary tools to write the code verses JRE provides with the environment in which the java code will run.
