Array is composite data type. A composite data type is one whose values are composed of component values (possibly values chosen from other data types.) Example of composite data type is array.

int a[ ] = {1,2,3,4,5};

在上面的示例中，据我所知，它是复合的，因为一个 array-of-int 值由从 int 类型中选择的一些元素值组成。使用复合数据类型，我们可以将多条相关数据作为单个数据进行管理。数组是使用以相同数据类型声明的多个值的概念。

请简单说明数组是复合数据类型。用例子解释这个说法？

最佳答案

A class defined with various primitive data types such as int, double etc;but i am using only one data type for array initialization that is int

考虑以下示例:

class Test {
    int a, b, c;
    Test() {
        a = 1 ; b = 2 ; c = 3;
    }
}

class Main {
    public static void main(String[] args) {
        Test object = new Test();
    }
}

根据您的定义，在这种情况下，即使类 Test 也将是原始数据类型，因为它只有 int 类型的值。然而，事实并非如此。

正如@Henry 所说，

The element types are irrelevant, important is only that there are several elements

所以基本上，我想说复合数据类型的更精确定义是:

The data types which are created by the user, which may consist of one or more primitive data types, created under a single declaration are called Composite data types.

根据该定义，数组也是复合数据类型。
