Install Oracle jdk__oracle under OpenSUSE 42.1

The OpenSUSE system has its own openjdk, but I would like to install it with the JDK provided by Oracle.

Method:

Download JDK:
jdk-8u65-linux-x64.rpm

Install JDK: Unzip the downloaded JDK, place it where you need it: Vi/etc/profile, add the following code at the end:

java_home=/run/media/xiamingchen/tools/jdk1.8/
Jre_home=/run/media/xiamingchen/tools/jdk1.8/jre
PATH=$ PATH: $JAVA _home/bin: $JRE _home/bin
classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar: $JRE _home/lib

Note Replace the path in it.
3. Use of command: Source/etc/profile
4. Use command: Update-alternatives--config Java, there will be several installed Java version, select our own installed JDK to set the number of the highest priority.

At this point, the installation is complete.

Check:
Enter at the end of the terminal: Java-version, the installed JDK version information is visible.
