java - 我如何在java中分割我的输入值

Question

import java.util.Scanner;

public class Main_Code {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.println("please input dice value");
        String pattern;
        pattern = input.nextLine();
        String[] parts = pattern.split("[d][-]");
        String part1 = parts[0];
        String part2 = parts[1];
        String part3 = parts[2];

        System.out.println(
            "The Pattern is : " + pattern + "\n" +
            "Number of dice : " + part1 + "\n" +
            "Number of dice surface : " + part1 + "\n" +
            "Card numbers is : " + part3);

我会用扫描仪输入(**2d6-4, 3d6-3**)这种类型的值。现在我想分割2d6-4(骰子数量:2，骰子面数:6，牌数是4)我该如何分割？

Answer 1

您可以使用正则表达式并拆分为多个标记:

 final String input = "2d6-4";
 final String[] tokens = input.split("-|d");
 System.out.println(Arrays.toString(tokens));

输出将是一个数组，如下所示:

[2, 6, 4]

骰子、表面、卡片......
