如果只是要看虚拟机的内存使用情况可以用
long tr = r.totalMemory();
//Returns the total amount of memory in the Java Virtual Machine.

long fr = r.freeMemory();
//Returns the amount of free memory in the system.

程序如下：
public class ShowMemory
{

  public static void main(String[] args)
  {
    java.lang.Runtime r =java.lang.Runtime.getRuntime();
    long tr = r.totalMemory();
    long fr = r.freeMemory();
    System.out.println("total:"+tr );
    System.out.println("free :"+fr );
  }
}
