Java中数组的静态初始化和动态初始化

public class Test{
    public static void main(String[] args) {
        // 静态初始化，创建+赋值
        int[] a = {1,2,3,4,5,6,7,8};
        System.out.println(a[0]);

        // 动态初始化,包含默认初始化
        int[] b = new int[10];
        int sum = 0;
        // 数组元素赋值
        for (int i = 0; i < numbers.length; i++){
            numbers[i] = i + 1;
            sum += numbers[i];
        }
        System.out.println(sum);
    }
}
