我正在尝试安装 Java 7。我先测试了我的 Java 版本，请看下面的代码
ubuadmin@ubuserver3:~/JavaJars/HelloWordGPU$ java -version
java version "1.6.0_30"
OpenJDK Runtime Environment (IcedTea6 1.13.1) (6b30-1.13.1-1ubuntu2~0.12.04.1)
OpenJDK Client VM (build 23.25-b01, mixed mode, sharing)
我尝试使用以下命令先卸载它:
sudo apt-get remove openjdk-6-jdk
它给了我以下结果。
ubuadmin@ubuserver3:~/JavaJars/HelloWordGPU$ sudo apt-get remove openjdk-6-jdk

Package openjdk-6-jdk is not installed, so not removed

ubuadmin@ubuserver3:~/JavaJars/HelloWordGPU$
我也尝试过使用 sudo apt-get remove default-jdk 但相同。
那么如何安装 Java 7？
