Question

NetBeans IDE has a taskbar indicaror, showing how much RAM is currently allocated and used by the running instance. How can I get this data in my own application written in Scala? If there’s no special function for this in Scala, I could use Java one.

Answer 1

private val runtime = Runtime.getRuntime()
import runtime.{ totalMemory, freeMemory, maxMemory }

 System.out.println("New session, \ 
    total memory = %s, max memory = %s, free memory = %s".format(
        totalMemory, maxMemory, freeMemory))
