示例1: testForEachKeyInParallel
import java.util.concurrent.ConcurrentHashMap; //導入方法依賴的package包/類
/**
* forEachKeyInParallel traverses all keys
*/
public void testForEachKeyInParallel() {
LongAdder adder = new LongAdder();
ConcurrentHashMap<Long, Long> m = longMap();
m.forEachKey(1L, (Long x) -> adder.add(x.longValue()));
assertEquals(adder.sum(), SIZE * (SIZE - 1) / 2);
}
