This video show how to install Java on Linux. Ubuntu is used in the demo, but in the video it can be seen how the technique applies to most popular Linux distributions that run Java. The Open Java version 8 is demonstrated using the Aptitude Package Manager for Ubuntu. The APT package manager can install Java in any Linux distribution that uses APT such as Debian, Kali and others. Also, the YUM package manager for RedHat and CentOS distributions can install Java using similar commands. The different between Oracle Java and Open Java is explained along with the difference between headless and full installations..
The webpwnized YouTube channel is dedicated to information security, security testing and ethical hacking. There is an emphasis on web application security but many other topics are covers. Some of these include forensics, network security, security testing tools and security testing processes. The channel provides videos to encourage software developers and system administrators to perform security testing. Also, the channel educates the next generation of security testers and bug bounty hunters who want to respectfully, legally and ethically help system owners that allow security testing.
