**回答**: 在 Elementary OS Luna 安装 Java 7 的步骤如下: 由于Elementary OS是基于Ubuntu，所以我们允许使用具有多种Java包的**WEPUD8 PPA**。


1. 打开终端。
2. 运行以下指令添加Java的PPA到你的软件仓:



```
$ sudo add-apt-repository ppa:webupd8team/java

You are about to add the following PPA to your system:
Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK6 / JDK7 / JDK8). There are no actual Java files in this PPA. More info: http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html
Debian installation instructions: http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html
More info: https://launchpad.net/~webupd8team/+archive/java
Press [ENTER] to continue or ctrl-c to cancel adding it

```
3. 按回车继续



```
gpg: keyring `/tmp/tmpB5WwDG/secring.gpg' created
gpg: keyring `/tmp/tmpB5WwDG/pubring.gpg' created
gpg: requesting key EEA14886 from hkp server keyserver.ubuntu.com
gpg: /tmp/tmpB5WwDG/trustdb.gpg: trustdb created
gpg: key EEA14886: public key "Launchpad VLC" imported
gpg: Total number processed: 1

OK

```
4. 现在更新你的系统



```
$ sudo apt-get update
