通过下图可以看出,除了在稀疏度为1时,EWAHCompressedBitmap内存占用最低以外,其余稀疏度下的内存占用:RoaingBitmap<EWAHCompressedBitmap<BitSet。 cpu耗时测试 往各个Bitmap中添加1、N+1、2N+1...5000000数据,其中N为数据的步长(稀疏度),然后与有5000000满数据的Bitmap分别求2000次差集并取2000次中的最大耗时,得...
又比如: Map<String, Order> map = new HashMap<String, Order>(); map.put("Order", (Order) obj); 资料: Collection容器中包含Set和List接口,Set中又包含HashSet,List中包含LinkedList和ArrayList;单独的Map接口中只有HashMap。 java.util 中的集合类包含Java中某些最常用的类。 最常用的集合类是 List 和...
步骤1:创建两个 Map 实例 首先,我们需要创建两个 Map 实例,用于比较差异。 AI检测代码解析 // 创建第一个 Map 实例Map<String,String>map1=newHashMap<>();map1.put("key1","value1");map1.put("key2","value2");// 创建第二个 Map 实例Map<String,String>map2=newHashMap<>();map2.put("k...
