Java Question

javac does not work in ubuntu terminal

When I try to compile a java program with

javac
, I get an error:

The program 'javac' can be found in the following packages:
* default-jdk
* ecj
* gcj-4.6-jdk
* gcj-4.7-jdk
* openjdk-7-jdk
* openjdk-6-jdk
Try: sudo apt-get install <selected package


When I try java -version, it says,

java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (7u21-2.3.9-1ubuntu1)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)


When I try which java I get
/usr/bin/java


How do I compile my java program from commandline?

Answer Source

As mentioned by @Blorgbeard you most likely do not have a Java JDK (Java Development Kit) installed. See this web page for more information about the various versions of Java available for Ubuntu.

The following command will install the OpenJDK version of the Java JDK:

apt-get install default-jdk
