Sudo add-apt-repository ppa:webupd8team/java To install any version, first execute the following commands: sudo apt-get install python-software-properties The Oracle JDK is the official JDK however, it is no longer provided by Oracle as a default installation for Ubuntu.
If you instead need the Java Development Kit (JDK), execute the following command: sudo apt-get install openjdk-7-jdk
This will install the Java Runtime Environment (JRE). To install OpenJDK 7, execute the following command: sudo apt-get install openjdk-7-jre That is everything that is needed to install Java. If you instead need the Java Development Kit (JDK), which is usually needed to compile Java applications (for example Apache Ant, Apache Maven, Eclipse and IntelliJ IDEA execute the following command: sudo apt-get install default-jdk If it returns "The program java can be found in the following packages", Java hasn't been installed yet, so execute the following command: sudo apt-get install default-jre Then, check if Java is not already installed: java -version First, update the package index: sudo apt-get update Following is the detailed process which covers almost all possible failures. I think you should consider Java installation procedure carefully. Repeat the above for: sudo update-alternatives -config javac Press enter to keep the current choice, or type selection number: 3 update-alternatives: using /usr/lib/jvm/jdk1.7.0_75/bin/java to provide /usr/bin/java (java) in manual mode * 0 /usr/lib/jvm/java-6-oracle1/bin/java 1047 auto modeĢ /usr/lib/jvm/java-6-oracle1/bin/java 1047 manual modeģ /usr/lib/jvm/jdk1.7.0_75/bin/java 1 manual mode There are 3 choices for the alternative java (providing /usr/bin/java). Now try: $ sudo update-alternatives -config java Sudo update-alternatives -set javaws /home/xxxxx/sipTest/jdk1.8.0_201/bin/javaws Sudo update-alternatives -set javac /home/xxxx/java/sipTest/jdk1.8.0_201/bin/javac sudo update-alternatives -set java /home/xxxx/sipTest/jdk1.8.0_201/bin/java Tell Ubuntu that our installation i.e., jdk1.8.0_05 must be the default Java. Sudo update-alternatives -install /usr/bin/javaws javaws /home/xxxx/java/jdk1.8.0_201/bin/javaws 20000 Sudo update-alternatives -install /usr/bin/javac javac /home/xxxx/java/jdk1.8.0_201/bin/javac 20000 sudo update-alternatives -install /usr/bin/java java /home/xxxx/java/jdk1.8.0_201/bin/java 20000 Let Ubuntu know where our JDK/JRE is located. Set path JAVA_HOME=path of your jdk folder(open jdk folder then right click on any folder, go to properties then copy the path using select all) like: /home/java(Folder name created by user in home directory).
