I would like to make a java app that shows the current battery level of my mac OS X.

I have read get OS-level system information and was wondering how I could modify this to make it display the current % of battery

Thanks

解決方案

I think you have two options.

One is to use JNI to invoke native code to get the battery level.

The other is to invoke the application pmset using System.exec in java and parse the output. I think the arguments to retrieve the battery level is pmset -g ps but you better check the man page
