Java ACM包

Question

I'm trying to write a java application in Eclipse.

I'm really wanting to use the ACM.Program package, however, my copy of Eclipse doesn't have it installed!

I've looked all over the net, and I can't find a single download for the ACM package.

More info: Whenever I try the code:

package helloGeiodo;
import acm.program.*;

public class Add2 extends Program {

   public void run() {
      println("This program adds two numbers.");
      int n1 = readInt("Enter n1: ");
      int n2 = readInt("Enter n2: ");
      int total = n1 + n2;
      println("The total is " + total + ".");
   }

} 

I get errors up and down the ying-yang, all implying that there is no such thing as "acm.program".

Anyways, I need to know where to find the ACM package, and, how to install it.

Thanks!

Answer 1

You can download acm.jar from the ACM Java Task Force and then add it to your classpath .

It appears that the previous link is dead. The files are still available at Eric Roberts' Stanford page .

Answer 2

The general answer is:

1. Download the JAR files from the relevant site
2. Copy (or import) them into your Eclipse project. People often put external JARs into a lib directory, but that's just a personal choice.
3. Add them to the project's build path.

However, I wouldn't recommend using the "ACM" classes. They were an interesting idea, but they didn't catch on.

Answer 3

如果您遵循斯坦福课程，您可以直接将作业（.zip文件）导入新的Java项目。

Answer 4

jtf.acm.org他们让你在那里下载它。
