Nettet7. apr. 2024 · 静态初始化:int[] arr = {1,2,3,4,5}; 动态初始化:int[] arr = new int[3]; 静态初始化:手动指定数组的元素,系统会根据元素的个数,计算出数组的长度。 动态初始化:手动指定数组长度,由系统给出默认初始化值。 使用场景: Nettet因此,这里的 arr 是3个元素的数组,其中每个元素都是4个整数的一维数组。 在我们正式开始讨论之前,声明一些共识: ①数组变量的名字表达第一个元素的地址,但是数组的 … Nettetint[] intArray1 = new int[1]; Arrays.asList(intArray1);//编译不报错 List list1 = Arrays.asList( intArray1);//编译报错 答案: 第二行代码, Arrays.asList()方法的入参是个引用类型的 int[],那么返回值类型一定是 List,其完整代码是: List intsArray = Arrays.asList(intArray1);,所以编译通过,没问题。 第三行报错,因为等号两边的类型 … low poly male model free
