Java

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Interactive Usage

After connecting to ShARC (see Establishing a SSH connection), start an interactive session with the qrsh or qrshx command.

The default version of Java (which is also the most recent version; currently 1.8.0_102) is made available with the command

module load apps/java

Alternatively, you can explicitly load this version using:

module load apps/java/jdk1.8.0_102/binary

Explicitly loading a version will become more useful once multiple versions of Java are installed on this system.

Check that you have the version you expect. First, the runtime

$ java -version

java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

Now, the compiler

$ javac -version

javac 1.8.0_102

These are primarily for administrators of the system.
