Take the Test.java under the org directory as an example:
1. Open the command line so that the current directory is ORG, then compile TEST.JAVA files: javac -d. Test.java
The result will generate a TEST folder under ORG.
3. Enclose a text file in the org directory, the content is as follows:
Manifest-Version: 1.0
Created-by: 1.4.2 (Sun Microsystems Inc.)
Main-class: test.test
Save as a manifest.mf file
4. In the command line, use the command: jar -cvfm helloworld.jar manifest.mf test
The result will generate a new.jar file under the ORG folder.
It should be noted:
(1) Main-class corresponds to the public class name (including the package name)
(2) JAR's parameters can be viewed directly with JAR, and details will not be described here.
Test.java source program:
Package test;
Import javax.swing. *;
Public Class Test
{
Public static void main (string [] args)
{
JFrame JF = New Jframe ("Welcome");
Jf.setsize (600,500);
Jf.setvisible (TRUE);
Jf.setDefaultCloseOperation (jframe.exit_on_close);
}
}
