Advertisements

In this article, I will take you through OpenJDK Installation on CentOS 7 with easy steps.

OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). It is the result of an effort Sun Microsystems began in 2006.

The implementation is licensed under the GNU General Public License (GNU GPL) version 2 with a linking exception. Were it not for the GPL linking exception, components that linked to the Java class library would be subject to the terms of the GPL license. OpenJDK is the official reference implementation of Java SE since version 7.

OpenJDK Installation on CentOS 7 is fairly easy and straightforward.

[root@localhost ~]# vi HelloWorld.java
class HelloWorld
{
public static void main(String[] args)
{
System.out.println("Hello World\n");
}
}

 

Step 7: Compile your HelloWorld Program

[root@localhost ~]# javac HelloWorld.java
[root@localhost ~]#
