Answer: Install java and check your path:
下载oracle7 jdk在：
http://www.oracle.com/technetwork/java/javase/downloads/java-se-jdk-7-download-432154.html
按照以下说明：
http://www.webupd8.org/2011/09/how-to-install-oracle-java-7-jdk-in.html例如
下载java(上)后：将下载的Oracle Java JDK归档解压缩到主文件夹,并将新创建的文件夹重命名为“java-7-oracle”.
sudo mv its_name java-7-oracle
安装它：
cd sudo mkdir -p /usr/lib/jvm/ #just in case sudo mv java-7-oracle/ /usr/lib/jvm/ sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install update-java sudo update-java
核实：
java -version javac -version
