@ohos.util.HashMap.get

官方API文档

测试用例 1: 测试HashMap容器get接口

function test_get(loopCount: number) {
  let hashMap = new HashMap<number, number>();
  for (let i = 0; i < loopCount; i++) {
    hashMap.set(i, 1);
  }
  const startTime = new Date();
  for (let i = 0; i < loopCount; i++) {
    hashMap.get(i);
  }
  const endTime = new Date();
  const executionTime = endTime.getTime() - startTime.getTime();
  const averageTime = executionTime / loopCount;
  console.log(`!${test_id}: ${averageTime} ms`);
}

@ohos.util.HashMap.hasKey

官方API文档

测试用例 1: 测试HashMap容器的hasKey接口（最好情况），HashMap长度为1000000

function test_hasKey1(loopCount: number) {
  let hashMap = new HashMap<number, number>();
  for (let i = 0; i < 1000000; i++) {
    hashMap.set(i,1)
  }
  const startTime = new Date();
  for (let i = 0; i < loopCount; i++) {
    hashMap.hasKey(0)
  }
  const endTime = new Date();
  const executionTime = endTime.getTime() - startTime.getTime();
  const averageTime = executionTime / loopCount;
  console.log(`!${test_id}: ${averageTime} ms`);
}

测试用例 2: 测试HashMap容器的hasKey接口（最坏情况），HashMap长度为1000000

function test_hasKey2(loopCount: number) {
  let hashMap = new HashMap<number, number>();
  for (let i = 0; i < 1000000; i++) {
    hashMap.set(i,1)
  }
  const startTime = new Date();
  for (let i = 0; i < loopCount; i++) {
    hashMap.hasKey(1000000)
  }
  const endTime = new Date();
  const executionTime = endTime.getTime() - startTime.getTime();
