How should I upgrade my Java compiler
提问by Eric Baldwin
When I run $ javac Simulator.javathen I get the following warning:
当我运行时，$ javac Simulator.java我收到以下警告：
warning: ./particle_simulator/Atom.class: major version 51 is newer than 50, the highest major version supported by this compiler.
warning: ./particle_simulator/Atom.class: major version 51 is newer than 50, the highest major version supported by this compiler.
I don't know why I suddenly get this warning as I haven't made substantial changes to my code. Nevertheless, how do I upgrade my Java compiler?
我不知道为什么我突然收到此警告，因为我没有对我的代码进行实质性更改。然而，我该如何升级我的 Java 编译器？

Download the JDK from Oracle: http://www.oracle.com/technetwork/java/javase/downloads/. Make sure you get the OSX version. It has its own installer so installation should be pretty straight forward.
