Java layman uses Python to tune Java,

First, install the Java Environment (Linux)

1. The first thing to do is download the official website of Jdk,java SE 8 is http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

2 TAR-ZXVF jdk-8u102-linux-x64.tar.gz

3 then we'll create a new directory and move the extracted files to the past.

Mkdir/usr/java

mv./jdk1.8.0_102/usr/java

4 First use Vim to open the/etc/profile file

5 added at the end of the document

java_home=/usr/java/jdk1.8.0_102

Export classpath= $JAVA _home/lib: $JRE _home/lib: $CLASSPATH

Export path= $JAVA _home/bin: $JRE _home/bin: $PATH

6. Make the configuration effective: Source/etc/profile

7 Viewing the Java version

Java-version

Two installation Python-related installation packages

# pip Install JPype1

Depend on:

Yum install-y wget gcc gcc-c++ python-devel mysql-devel bzip2 Python-pip

Iii. generating A. class file

Javac-encoding Utf-8 Desedeservice.java

Iv. Call

# create a consistent directory structure based on the explicit directory structure in the. java file and put the. java file in the specified location # Execute javac-encoding utf-8 xxx.java build. class file in the same directory as the. java file " -ea " " -djava.class.path=/data/monitor/src "  = Jpype.
