java LongAdder 和 AtomicLong 累加 测试比较

package atomadder;

import java.text.MessageFormat;
import java.util.concurrent.atomic.AtomicLong;
import java.util.concurrent.atomic.LongAdder;
import java.util.logging.Logger;

public class test {
	private static Logger logger = Logger.getLogger("LoggingDemo");
	public static void atomicLong() throws Throwable {
        final int threadCount = 32;
        final AtomicLong longValue = new AtomicLong();
        Thread[] threads = new Thread[threadCount];
        for(int i=0; i
