This article focuses on "how to execute java programs under Linux". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to execute java programs under Linux.

If you want to run the java program on ubuntu, you can compile the java program and package it, and then execute the jar file on ubuntu with the command

The specific operations are as follows:

1. Use eclipse to compile the java project on windows, and export it to runnable jar file after compilation

For example, here the test2 file in the test project is export to a mytest2.jar file

2. Install the java environment on ubuntu

① jdk official website http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html downloads jdk for use on linux

② eclipse official website http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/heliossr1/ downloads eclipse for use on linux

③ uploads jdk and eclipse to the linux server and decompresses them, and then configures the java environment variable (the extracted directory for eg.jdk is / home/test)

Configuration method: edit the / etc/profile file and add the following (Note: colon in linux: used to separate paths, periods. Represents the current directory)

Export java_home=/home/test/jdk1.8.0_65

Export path=$java_home/bin:$path

Export classpath=.:$java_home/lib/dt.jar:$java_home/lib/tools.jar

Save the file after editing

④ makes the configuration effective, command source / etc/profile

⑤ tests whether the environment variable is configured successfully, and commands java-version

If the jdk version is displayed, the java environment variable is configured successfully.

3. Jar file exported by java project on ubuntu

Command: java-jar mytest2.jar
