Is there any possibility to count the working time of a processes in java?

for example in a pseudo code

for(some Object:all Objects){
startProcess1();
....
startProcessn();}
if(startProcess1 is finished){
getTimeOfProcessOne()}

Thanks

Processing time of a thread/objects in java can be determined as 

ThreadMXBean bean=ManagementFactory.getThreadMXBean();
long id=Thread.currentThread().getId();
long start,end;
if(!bean.isThreadCpuTimeSupported()){System.exit(0);}
start=bean.getThreadCpuTime(id);

//Call some methods , process some objects

end=bean.getThreadCpuTime(id)-start;

Now end will contain processing time of Thread with ID as id. This time will be in NanoSeconds.
