随机数数组里的各个元素相加的和该怎么用代码表示？

int[] array = new int[3];
for(int i = 0;i < array.length;i++) {
    int random = (int)(Math.random()*6) + 1;            
    array[i] = random;
    System.out.println(array[i]);
}

public static void main(String[] args) {
        int[] array = new int[3];
        int sum = 0;
        for (int i = 0; i < array.length; i++) {
            int random = (int) (Math.random() * 6) + 1;
            array[i] = random;
            sum += random;
            System.out.println(array[i]);
        }
        System.out.println("sum: " + sum);
    }

运行效果

int[] array = new int[3];
int sum = 0;
for(int i = 0;i < array.length;i++) {
int random = (int)(Math.random()*6) + 1;
array[i] = random;
sum += random;
System.out.println(array[i]);
}
System.out.println("和为：" + sum );
