Find the Number of Processors Available

There are abundant resources available in the java.lang package. Learn more about the server/host on which you are working.

The Runtime class has numerous functionalities. To learn the number of processors that are available, we can use the following:

public class CPUsCount
public static void main(String args[])
CPUsCount cPUsCount = new CPUsCount();

private void proceed()
//Returns the count of processors in the host that this application is run
System.out.println("Availabe processor count: " + Runtime.getRuntime().availableProcessors());


Expected output:

[root@mypc]# java CPUsCount
Availabe processor count: 4
