思想： 用户输入'W'，'L'或'T'（胜利，亏损或平局）来下注。程序在这些参数中生成随机结果。打印用户输入和结果，并根据程序提供的正确投注显示分数。
我在如何继续将用户生成的扫描仪输入与产生随机结果的arraylist进行比较时遇到问题。
如果不是多个“问题”和“答案”，我可以使用(val.equals(input))排序。但是，每个单独的投注都是随机的，必须与用户投注相匹配才能总结用户得分，这会使其复杂化。
任何帮助表示赞赏。

为简单起见，我删除了test3，但基本上你需要在数组上保存结果并生成随机结果并保存它们（即列表）。然后你必须迭代并比较每个游戏结果，如果你的投注是正确的，只需加一个得分。检查以下代码：
public static void main(String[] args) {
int score = 0;
String array[] = new String[5];
List < String > randomResultList = new ArrayList<String> ( );
System.out.println("Betting game initiating... \nType 'W' for win, 'L' for loss and 'T' for tie.");
Scanner input = new Scanner(System.in);
for (int i = 0; i < 5; i++)
{
System.out.println("Please enter your bet:");
array[i]=input.nextLine();
}
System.out.println("This week wins, losses and ties loading...\n");
System.out.println("Result:");
for(int i = 0; i < 5; i++){
String randomResult = getRandomList();
System.out.print( randomResult + " ");
randomResultList.add ( randomResult );
}
System.out.println("\n\nYour bets were:");
for (int i = 0; i < 5; i++){
System.out.print(array[i] + " ");
}
//here is where you compare each result
for(int i = 0; i < 5; i++)
{
if( array[i].equals ( randomResultList.get ( i ) ))
{
score++;
}
}
System.out.println("\n\nYou were correct on: " + score + " bettings");
}
private static Random random = new Random();
public static String getRandomList() {
List<String> list = Arrays.asList("w", "l", "t");
int index = random.nextInt(list.size());
return list.get(index);
}
投注游戏开始...
键入＆＃39; W＆＃39;为了胜利，＆＃39; L＆＃39;对于损失和＆＃39; T＆＃39;为了领带。
请输入您的投注：

请输入您的投注：

请输入您的投注：

请输入您的投注：

本周获胜，失利和关系加载......
结果：
l l l t w
你的赌注是：
w w w w w 你是对的：1次投注
您可以在同一次迭代中完成所有操作！看看这个。
public static void main(String[] args) {
int score = 0;
// Win Loose or Tie
List<String> list = Arrays.asList("w", "l", "t");
Random rand = new Random ( );
//String with result and bets i.e (wwwww) and (wlltw). This avoid another iteration.
String result="";
String bets = "";
System.out.println("Betting game initiating... \nType 'W' for win, 'L' for loss and 'T' for tie.");
Scanner input = new Scanner(System.in);
for (int i = 0; i < 5; i++)
{
System.out.println("Please enter your bet:");
String bet =input.nextLine();
String randomResult = ( list.get ( rand.nextInt ( list.size ( ) ) ));
//concatenate String with results and bets with +=
result += randomResult;
bets += bet;
//check if u won
if( bet.equals ( randomResult ))
{
score++;
}
}
//This are just the results! no more iterations.
System.out.println("This week wins, losses and ties loading...\n");
System.out.println("Result:" + result);
System.out.println("\n\nYour bets were:" + bets );
System.out.println("\n\nYou were correct on: " + score + " bettings");
}

执行此操作的一种方法是在下面的代码中。
您基本上需要将输入的每个元素与随机列表的每个元素进行比较，以便运行循环。
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Random;
import java.util.Scanner;
public class Test {
private Random random = new Random();
public static void main(String[] args) {
int score = 0;
System.out
.println("Betting game initiating... \nType 'W' for win, 'L' for loss and 'T' for tie.");
Scanner input = new Scanner(System.in);
String array[] = new String[5];
for (int i = 0; i < 5; i++) {
System.out.println("Please enter your bet:");
array[i] = input.nextLine();
}
System.out.println("\n\nYour bets were:");
for (int i = 0; i < 5; i++) {
System.out.print(array[i] + " ");
}
List<String> list = new ArrayList<String>();
list.add("w");
list.add("l");
list.add("t");
System.out.println("This week wins, losses and ties loading...\n");
System.out.println("Result:");
Test obj = new Test();
List<String> randList = new ArrayList<>();
for (int i = 0; i < 5; i++) {
randList.add(obj.getRandomList(list));
}
for(String randBet : randList){
System.out.print( randBet + " ");
}
System.out.println("");
int counter = 0;
for (String yourbet: Arrays.asList(array)){
if(randList.get(counter).equals(yourbet)){
score++;
}
counter++;
}
System.out.println("\n\nYou were correct on: " + score + " bettings");
}
public String getRandomList(List<String> list) {
int index = random.nextInt(list.size());
return list.get(index);
}
}
