Java 使用将被调用回程序的字典程序调用翻译程序

我是一个完全不懂编码的人，我想知道我是否能得到一些帮助

我有这个项目，基本上我需要做的是：

创建2个可执行程序。翻译程序和字典程序。这些程序可以用任何语言编写

翻译程序将向词典程序传递一个英语单词。字典程序将翻译并返回一个外来词。翻译程序将打印出英文单词并将其翻译成文件

字典程序将查找英文单词并返回其外文翻译。词典程序将能够将选定数量的英语单词翻译成另一种语言。词典程序翻译英语单词的语言将由学生决定。字典程序将有能力将至少15个英语单词翻译成外语

现在我很难让字典程序调用翻译程序。 我的指导老师告诉我们使用这个语句

Process proc = Runtime.getRuntime().exec("java -jar Translate.jar"); 

InputStream in = proc.getInputStream();
InputStream err= proc.getErrorStream();

目前的问题是，我的程序似乎无法访问jar文件。 我正在使用Eclipse和Windows7 我创建Translate jar文件的步骤是

在“翻译”项目上单击鼠标右键 出口 选定的可运行Jar文件 选择Dictionary-Dictionary作为启动配置 输入Dictionary\Translate.jar作为导出目标 单击finish，然后继续尝试使用Process runtime 现在我只有两个程序的伪代码，但我专注于找出如何调用translate程序

Dictionary.java Translate.java

如果我不被允许接受如此多的帮助，有人能告诉我还有哪些网站允许我发布此请求吗？

我的导师告诉我们使用该语句是本练习的重点，以了解如何使用进程或如何将基于Java的类连接到另一个jar中的另一个Java类？后者更有用、更简单。我相信是后者，因为他说他只建议使用过程。然而，这似乎是我认为最有效的一个，因为我的其他同学都在使用它。然后我又问了一遍，我不知道还有什么更好的。但是，项目的主要目的是以jar文件的形式调用另一个基于java的类

public class Dictionary {

    public static void main(String [] args){

        /******************

         * Will translate and return a foreign word back 
         * to the Translate program that this Program is calling.
