Java实验：计算键盘输入三个数的和以及平均值

重点是获取键盘输入的值
Scanner scanner = new Scanner(System.in);
int sum=scanner.nextint();

下面贴出完整代码

public class Average {    /**     * @param args     */    public static void main(String[] args) {        // TODO Auto-generated method stub        int sum = 0;        int aver = 0;        Scanner scanner = new Scanner(System.in);        for (int i = 1; i < 4; i++) {            System.out.print("请输入第" + i + "学生的成绩：");            sum += scanner.nextInt();            aver = sum / i;        }        System.out.println("成绩和是" + sum);        System.out.println("平均成绩是" + aver);    }}
