检测OutOfMemoryError是否可以被捕捉

/**

package overload;

import java.util.HashSet;

public class OutMemory {

	/**

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		long t = 0;
		try{
			HashSet total = new HashSet(1000000);
			for(;;){
				System.out.println("["+(t++)+"]");
				HashSet ss = new HashSet(1000000);
				ss.add(new Object());
				total.add(ss);
			}
		}catch(Exception e){
			e.printStackTrace();
		}
	}

}


平台打印的东东

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
	at java.util.HashMap.<init>(Unknown Source)
	at java.util.HashMap.<init>(Unknown Source)
	at java.util.HashSet.<init>(Unknown Source)
	at overload.OutMemory.main(OutMemory.java:28)


事实证明可以被捕捉的

      java.lang.Error
          java.lang.VirtualMachineError
              java.lang.OutOfMemoryError

你的这个是怎么catch住的?

多谢指点~，我这边的理解错了
