This is the journey of the editor's growth path, and also the editor's learning path. Hope to grow up with you guys!

Here are two of my favorite quotes:

To have the most simple life and the most distant dream, even if it will be cold tomorrow, the mountains will be high and the water will be far away, and the road will be far away.

Why should one work hard? The best answer I have ever seen is: because the things I like are expensive, the places I want to go are far away, and the person I love is perfect. Therefore, the editor would like to say: encourage each other!

try: apt install <selected packages>

problem causes:

1) It may be that the java environment variables are not configured properly, check JAVA_HOME, JRE_HOME, CLASSPATH, PATH

2) Did not download jdk

Solution:

Open the vim ~/.bashrc file and add the following configuration at the end

#set oracle jdk environment
export JAVA_HOME=/usr/local/jdk1.8.0_371  ## 这里要注意目录要换成自己解压的jdk 目录
export JRE_HOME=${JAVA_HOME}/jre  
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib  
export PATH=${JAVA_HOME}/bin:$PATH 

 Then enter java -version to see if the above problem still occurs
