【Java编程|如何在ubuntu提高jdk版本】The easy way
The easiest way to install the JDK 7 is to do it with the Web Up8 Oracle Java OOS. However, it is believed that this PPA is sometimes out of date. Also note the dangers of using a PPA.
This installs JDK 7 (which includes Java JDK, JRE and the Java browser plugin):
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
//or if you want JDK 8:
sudo apt-get install oracle-java8-installer
/* these commands install Oracle JDK7/8 and set them as default VMs automatically:*/
sudo apt-get install oracle-java7-set-default
sudo apt-get install oracle-java8-set-default
