Java第7次作业

1.

public class Hestia {

    public static void main(String[] args) {

        int[] arr = {3, 7, 5, 2, 1, 40};//定义数组

        int temp = arr[0];//定义一个整形，用于比较和接受最大值

        for (int i = 0; i < arr.length; i++) {//遍历数组

            if (temp < arr[i]) {//如果temp小，则将遍历到的数复制给temp
                temp = arr[i];
            }

        }

        System.out.print(temp);//输出最大值

    }

}
