Methods to execute Java programs under Linux

To run Java programs on Ubuntu, you can compile the Java program successfully, package it, and then execute the jar file using the command on Ubuntu

Specific operations are as follows:

1How to compile Java projects using eclipse on Windows, and export them as Runnable JAR File after compilation

For example, here the Test in the test project is exported as a Runnable JAR File2Export the file as MyTest2.jar file

2Ubuntu Java environment installation

①JDK official website http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html to download JDK for Linux

②eclipse official website http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/heliossr1/Download eclipse for Linux

③ Upload JDK and eclipse to the Linux server, unzip them, and then configure the java environment variables (e.g., the unzip directory of JDK is/home/test)

Configuration method: edit/etc/Add the following content to the profile file (Note: The colon : is used to separate paths in Linux, and the dot . 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 Make the configuration take effect, command source /etc/profile

⑤ Test if the environment variable is configured successfully, command java -version

If the JDK version is displayed, it means that the java environment variable is configured successfully

3Execute the jar file exported by the java project on Ubuntu

Command: java -jar MyTest2.jar
