Newbie on debian and trying to make Java 7 the default java version used
提问by Melinda
2 questions.
2个问题。
- After installing the Oracle Java 7 on my new Debian local box, I opened up a terminal and executed the following command:
- 在我的新 Debian 本地机器上安装 Oracle Java 7 后，我打开一个终端并执行以下命令：
java -version
版本
When I did that it states: java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)
当我这样做时，它指出： java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03) Java HotSpot(TM) Client VM（build 20.1-b02，混合模式，共享）
I installed the Java 7 JDK and Java 7 JRE in the following directories respectively:
我分别在以下目录中安装了 Java 7 JDK 和 Java 7 JRE：
/usr/lib/jvm/jdk1.7.0 /usr/lib/jvm/jre1.7.0
/usr/lib/jvm/jdk1.7.0 /usr/lib/jvm/jre1.7.0
- Is there a way to remove the java-6-sun and java-6-sun-1.6.0.26 folders as well or will it hurt just to leave them there?
- 有没有办法删除 java-6-sun 和 java-6-sun-1.6.0.26 文件夹，或者只是将它们留在那里会受到伤害吗？
Any help/direction on these 2 questions would be appreciated.
对这两个问题的任何帮助/指导将不胜感激。
Regards.
