java 键盘输入使用循环遍历数组方法实现求出输入的最大值

public class Demo02ScannerSum {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("请输入第一个数字：");
        int a = sc.nextInt();
        System.out.println("请输入第二个数字：");
        int b = sc.nextInt();
        System.out.println("请输入第三个数字：");
        int c = sc.nextInt();
        int[] num = {a, b, c};
        int d = num.length;
        int max = num[0];
        for (int i = 0; i < d; i++) {
            if (num[i] > max) {
                max = num[i];
            }
        }
        System.out.println("最大值为" + max);
