Download jdk from oracle needless to say

Tar zxvf * .tar.gz (* .tar.gz is the name of the downloaded file, decompress.)

Mv * jdk (* is the folder you unzipped, change your name, I change it to jdk, change whatever I like, I'll change this easy to remember)

Mv jdk / usr/local/ (then put the renamed folder in / usr/local/)

Vi / etc/profile (edit the configuration, environment variables)

Add at the end:

JAVA_HOME=/usr/local/jdk

Export JRE_HOME=/usr/local/jdk/jre

Export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH

Export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

Then modify the default JDK:

Update-alternatives-install / usr/bin/java java/ usr/java/bin/java 300

Update-alternatives-install / usr/bin/javac javac / usr/java/bin/javac 300

Update-alternatives-config java

Update-alternatives-config javac

Source / etc/profile

Java-version

Javac-version
