这是我第一次编码,所以我很抱歉,如果我让你面对面.

我想使用Scanner类来读取用户输入.但是,我收到一个错误.当我遇到这个问题时,我已停止编码,因此代码远未完成,但这就是我所拥有的:

package trigger;
import java.util.Scanner;
public class Trigger {
    public static void main(String[] args) {

        System.out.println("Please input known values");
        Scanner input = new Scanner(System.in);

        System.out.println("Angle A");
        String Ain = input.next();

        System.out.println("Angle B");
        String Bin = input.next();

        System.out.println("Angle C");
        String Cin = input.next();

        System.out.println("Side A");
        String ain = input.next();

        System.out.println("Side B");
        String bin = input.next();

        System.out.println("Side C");
        String cin = input.next();

    }
}

这会返回如下错误:
