harmony-utils之ObjectUtil，对象工具类harmony-utils 简介与说明harmony-utils 一款功能丰富且极易上手的HarmonyOS工具库，借助众多实用工具类，致力于助力开发者迅速构建鸿蒙应用...(user);getClassName 获取对象的Class名称let user: User = new User();let name1 = ObjectUtil.getClassName(user)...(user);let bl2 = ObjectUtil.isString(obj);isNull 判断对象是否为空let user: User = new User();let bl1 = ObjectUtil.isString...(user);let bl2 = ObjectUtil.isEmpty(obj);shallowCopy 浅拷贝let user: User = new User();let user1 = ObjectUtil.shallowCopy..."张若喃");ObjectUtil.setValue(user, "work", "女演员啊");ObjectUtil.setValue(user, "job", "女演员");

(3)编写Instrumentation Test程序，放在src/androidTest/java目录下 类ObjectUtil还是和前面的Unit Test中一样，只是添加一个新的测试类 import...objectUtil; private static final String fileName = "demo"; @Before public void setUp()...throws Exception { mMockContext = InstrumentationRegistry.getContext(); objectUtil =...new ObjectUtil(mMockContext); } @Test public void testNotNull() {//ok //can not...(user, fileName); user = (User) objectUtil.load(fileName); assertThat(user.name, is(

对象工具 - ObjectUtil # 6.1 ObjectUtil.equal 比较两个对象是否相等，相等需满足以下条件之一： Object a = null; Object b = null; /.../ true ObjectUtil.equals(a, b); # 6.2 ObjectUtil.length 计算对象长度，如果是字符串调用其 length 方法，集合类调用其 size 方法，数组调用其...> map = new HashMap(); map.put("a", "a1"); map.put("b", "b1"); map.put("c", "c1"); // 3 length = ObjectUtil.length...(map); # 6.3 ObjectUtil.contains 对象中是否包含元素。...(array, 1); # 6.4 判断是否为 null ObjectUtil.isNull ObjectUtil.isNotNull 注意：此方法不能判断对象中字段为空的情况，如果需要检查 Bean
