Unable to find/install the Java package acm.graphics

Question

I get the following error message

RobotFace.java:3: package acm.graphics does not exist
import acm.graphics.*; 
^

It suggests me that I do not have acm.graphics -package.

I have tried to find and install the package in MacPorts unsuccessfully by

port search acm

How can you install acm.graphics package in your computer for Java?

Answer 1

As stated in the answer below, you need the acm.jar file. Here's how to do it in 3 easy steps:
1. Under "downloads", download the acm.jar file here: Stanford's website .
2. See screenshots below. I'm using NetBeans for my IDE, but it should be more or less the same for any IDE. I right-clicked "libraries" and added the acm.jar file. (Note from screenshots: I took these screenshots after I installed the acm.jar file. You won't see this in your libraries folder until after you have completed this procedure.)
3. Refresh your project.

Answer 2

A quick Google search yielded http://jtf.acm.org/ .

Note there is a "acm.jar" file. You need to download that and add it to your CLASSPATH.
