我正在尝试在Ubuntu终端上运行javac.但我得到以下内容:
$ javac
The program 'javac' can be found in the following packages:
* openjdk-6-jdk
* ecj
* gcj-4.4-jdk
* gcj-4.6-jdk
* gcj-4.5-jdk
* openjdk-7-jdk
Try: sudo apt-get install <selected package>
jdk已经安装并正在运行sudo apt-get install openjdk-6-jdk说0 upgraded, 0 newly installed, 0 to remove and 322 not upgraded.
我的jdk安装在/ usr/lib/jvm/java-6-open-jdk中; 我能够从eclipse编译并运行一个java程序.但是在使用终端时我遇到了这个前面提到的问题.
