hi friend,

import java.util.*;
import java.util.logging.Logger;

public class ThreadMemory
implements Runnable{
public static Logger logger = Logger.getLogger(ThreadMemory.class.getName());

protected static Thread mainThread;
protected static int sleepSec;

public ThreadMemory() {
public ThreadMemory(int sleepSec)
this.sleepSec = sleepSec;

public static boolean isMonitorActive() {
return mainThread.isAlive();
return false;

public void startMonitor()
mainThread = new Thread(this, this.getClass().getName());

public void run(){"Started with polling = " + String.valueOf(sleepSec) + " sec");
while(true){"Free mem: " + String.valueOf(Runtime.getRuntime().freeMemory()));"Tot mem: " + String.valueOf(Runtime.getRuntime().totalMemory()));"Thread n: " + String.valueOf(Thread.currentThread().activeCount()));"");

// Sleeps (polling time):
try {

} catch (InterruptedException e){
System.out.println("errer threas sleeping"+ e);
} // end run

public static void main(String args[]){

ThreadMemory thread = new ThreadMemory();

System.out.println("Welcome roseindia");

In other words,i want to compute a C++_program's memory usage in java,
