此特定代码未读取作为字符串“s”给出的输入。如何纠正这个？ [复制]

Question

import java.util.Scanner;

public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        double d = scan.nextDouble();
        String s = scan.nextLine();

        System.out.println("String: " + s);
        System.out.println("Double: " + d);
        System.out.println("Int: " + i);
    }

}

Answer 1

你可以使用

 int i = scan.nextInt();
 scan.nextLine();
 double d = scan.nextDouble();
 scan.nextLine();
 String s = scan.nextLine();

请注意，Scanner.nextInt()、Scanner.nextDouble 等不会得到最后一行。所以你需要单独调用它们。
