你如何使用Java库？ [英] How do you use a Java Library?

问题描述

我正在尝试使用开源java库来可视化图形中的节点和边缘，但我完全迷失了。

我有一堆文件夹中的jar文件。点击一些jar文件可以弹出java swing窗口并显示图形。点击其他jar文件什么都不做。

如果我想出来的话，我会将jar文件与其他文件一起粘贴在那里，还是仍然不起作用？ / p>

如果我弄清楚如何使用这些文件，这是否意味着如果我将我的java项目转移到另一台计算机，我必须包含它们？我该怎么做呢？

解决方案

您是否已将这些库包含在类路径中？

如果你正在使用eclipse，你可以

项目 - >属性 - > Java构建路径 - > addJar。

Jar文件应放在工作区内的目录中（例如lib /）

如果必须将项目带到另一台计算机，您可以采取以下步骤

1. 在执行任何操作之前，请导出项目（例如，作为Jar文件）。


2. 将其保存到您最喜爱的驱动器（cd / usb驱动器/软盘/磁带）中。


3. 在另一台计算机上，您可以将此项目导入工作区

I'm trying to use an open source java library to visualize nodes and edges in a graph, but I'm completely lost.

I have a bunch of jar files in a folder. Clicking on some of the jar files makes java swing windows pop open with graphs displayed. Clicking other jar files does nothing.

If I figured that out, would I just stick the jar files in there with the other ones, or would that still not work?

And if I ever figure out how to use these files, does that mean that I have to include them if I transfer my java project to another computer? How would I go about doing that?

解决方案

Have you included those libraries in your classpath?

If you are using eclipse, you could

Project - > properties -> Java build path ->addJar.

And the Jar file should be placed in a directory inside your workspace (lib/ for example)

If you have to take your project to another computer, you could take these steps

1. Before doing anything, export your project (as a Jar file, for example).
2. Save it into your favorite drive (cd / usb drive/ diskette/ tape).
3. On "the other" computer, you can import this project into your workspace
