    下载好jdk后
    修改环境变量，编辑/ect/profile文件，将变量添加进去就好了

    使用sudo啊
    1. sudo gedit /etc/profile
    Copy the Code

    用这个命令编辑，然后保存重启就好了。不过我保存的变量重启不生效，不知道啥原因，保存在~/.bashrc中就可以

    1. 下载Sun版JDK压缩包（.tar.gz），选择其中的32/64位Linux版本。
    2. 将其解压缩：sudo tar -zxvf ~/Downloads/jdk-8u45-linux-i586.tar.gz -C /usr/lib 中参数-C后面的路径是解压缩的目标路径。
    3.sudo update-alternatives --install /usr/bin/java java /opt/jdk1.8.0_66/bin/java 1000
    sudo update-alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_66/bin/javac 1000

    参考官网：
    Starting with version 8u40, the JDK installation is integrated with the alternatives framework and after installation, the alternatives framework is updated to reflect the binaries from the recently installed JDK. Java commands such as java, javac, javadoc, and javap can be invoked from the command line.
