示例1: testReduceKeysSequentially
import java.util.concurrent.ConcurrentHashMap; //导入方法依赖的package包/类
/**
* reduceKeysSequentially accumulates across all keys,
*/
public void testReduceKeysSequentially() {
ConcurrentHashMap<Long, Long> m = longMap();
Long r;
r = m.reduceKeys(Long.MAX_VALUE, (Long x, Long y) -> Long.valueOf(x.longValue() + y.longValue()));
assertEquals((long)r, (long)SIZE * (SIZE - 1) / 2);
}
