Get the system properties from RuntimeMXBean in Java
RuntimeMXBean in the management interface for the runtime system of the Java virtual machine.
RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
To get the system properties, use the getSystemProperties() method −
System.out.println("System properties from RuntimeMXBean:
"+runtimeMX.getSystemProperties());The following is an example −
Example
import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
import java.util.Date;
public class Demo {
public static void main(String args[]) throws Exception {
RuntimeMXBean runtimeMX = ManagementFactory.getRuntimeMXBean();
System.out.println("System properties from RuntimeMXBean:
"+runtimeMX.getSystemProperties());
}
}Output
System properties from RuntimeMXBean:
