How to confirm that swing is installed [closed]

Question

In Ubuntu 9.10 is there any way to confirm/ check if swing is installed and thus check its version!

Answer 1

Swing will be included in the JVM, if it's new enough.

See this page.

Answer 2

If you are looking for a JRE to run a desktop application, you can check for the 'java' executable in $PATH, look for $JRE_HOME or $JAVA_HOME environment variables. Once a JRE is found use java -version to get its version.

If you are trying to deploy an applet, use the Java Deployment Toolkit.

Answer 3

Swing is included in the default Java JRE. So just:

sudo apt-get install openjdk-6-jre

If you need the JDK (to develop on), it's:

sudo apt-get install openjdk-6-jdk

As far as the version, it should be compatible with Java 6. You can check the exact package version with:

apt-cache show openjdk-6-jre

Answer 4

Here's the Java installation page for Ubuntu that covers everything from SDK to web browsers.

Answer 5

1. Open a terminal
2. Type: java -version

If it says something meaningful, you're fine; you have swing on that machine.
