以下代码中，输入2时result的值为：public static int getValue(int i) { int result = 0; switch (i) { case 1: result = result + i; case 2: result = result + i * 2; case 3: result = result + i * 3; } return result; }

• A、6
• B、2
• C、4
• D、10

答案：D

 

package test;

public class TestTest {

    public static void main(String[] args) {
        System.out.println(getValue(2));
    }

    public static int getValue(int i) {
        int result = 0;
        switch (i) {
            case 1:
                result = result + i;
            case 2:
                result = result + i * 2;
            case 3:
                result = result + i * 3;
        }
        return result;
    }

}
