Using acm.jar The ACM Java Task Force (JTF) created an API framework for Java programs which is distributed in the file acm.jar. Programs using acm.jar may be compiled and executed from the command line, or within your favorite Java IDE (e.g., Netbeans, DrJava). It is also possible to run your JTF programs as an applet within a browser or via the appletviewer. ````````````````````````````````````
