Ubuntu下java环境的安装与配置_JAVA_编程开发_程序员俱乐部

class="shell" name="code">#! /bin/bash


# 这个脚本用于在Ubuntu中配置java环境，包括JDK、eclipse和ant。
#
# 在使用这个脚本之前，你需要下载JDK、eclipse和ant。目前该脚本只能处理以.tar.gz为后缀的文件。下载时请注意。
#
# 下载完成后，将下载到的三个软件和这个脚本放在同一个文件夹下，最好新建一个文件夹。
#
# 修改脚本的运行权限(chmod u+x 脚本名)，然后在终端中执行该脚本，既可完成Ubuntu下java环境的安装与配置。
