我正在制作一个代码,该代码从用户那里取出卡片并将它们放入卡片组中,卡片的价值取决于数字,例如1然后5将是5心3然后13将是黑桃王。如果卡正确插入它应该返回true,如果不是它应该抛出异常,它应该检查甲板上的空间,如果没有它应该返回false,最后如果卡已经插入它应该返回false。错误在评论中。
import java.util.Scanner;
public static void main(String[] args){ //red underline error on void saying "syntax error token", under the second bracket of String[] and on the last bracket after args.
private static addCards(){
String suit[] = {"Hearts", "Diamonds", "Spades", "Clubs"};

"7", "8", "9", "10", "Jack", "Queen", "King"};

您正确使用||
if(inputSuit = 1 || 2 || 3 || 4 ){
这样做
if(inputSuit == 1 || inputSuit == 2 || inputSuit == 3 || inputSuit == 4 ){
||
用于执行布尔OR,一般用法是
((Boolean Expression 1) || (Boolean Expression 2) || (Boolean Expression 3)...)
同样纠正这个
if(inputValue = 1 || 2 || 3 || 4 || 5 || 6 || 7 || 8 || 9 || 10 || 11 || 12 || 13){
答案 1 :(得分:1)
您错过了public class [ClassName] {}
答案 2 :(得分:1)
我害怕有很多错误。您尚未定义一个类,该类应与文件名对应。您开始一个主方法,但在开始另一个方法之前不要关闭它的括号。你的if语句无效。
也许您应该花些时间学习初学者Java书籍或在线教程,然后在更好地理解Java语法后再回到这段代码。

答案 4 :(得分:0)
您的代码中有多个错误。
Class
。 main
方法中的另一种方法。 ||
运算符。检查@Ankit回答。=
代替==
。 =
是assignment
运算符,您需要的是comparison
运算符,即==
