How to path set in Ubuntu 15.04 of Java , download the version of java-8-oracle?

Question

I am new to Ubuntu. Recently we changed my OS to Ubuntu 15.04. I am installed java-7-openjdk-i386 from "Ubuntu Software Center" and when I use the "Android Studio" then it highly recommended me to use JDK1.7 or JDK1.8. After that I download the JDK1.8 "java-8-oracle" and set the path is as like that in $ gedit ~/.bsharc and I write that line to set the path:

JAVA_HOME=/usr/lib/jvm/java-8-oracle/bin
export JAVA_HOME
PATH=$PATH:$JAVA_HOME
export PATH

Solution

Install the JDK with a PPA:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

And after that

sudo apt-get install oracle-java8-set-default

Check the installation:

% java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

Later you can change the default Java with:

sudo update-alternatives --config java
