java - 1 秒计时器每秒激活多次

Question

试图用java制作一个cookie clicker风格的游戏。我是初学者，所以这很糟糕......这就是我所拥有的：

static double money = 50;
static double mps = 0; //money per second

public static void main(String[] args) throws InterruptedException{
    
    
    System.out.println("\n*You have $50*"
    + "\n*Use this money to make more money*"
    + "\n*Type \"stats\" To see what you can buy*");
    
    String statsString = "*Type Numbers To Buy, You Can Only Buy If You Have Enough Money!*"
            + "\n1 = $50 = 1 $/sec"
            + "\n2 = $100 = 2.2 $/sec"
            + "\n3 = $300 = 7.2 $/sec"
            + "\n4 = $1,200 = 31.2 $/sec"
            + "\n5 = $6,000 = 168 $/sec"
            + "\n6 = $36,000 = 1,080 $/sec"
            + "\n7 = $253,000 = 5,060 $/sec"
            + "\n8 = $2,024,000 = 68,816 $/sec"
            + "\n9 = $18,216,000 = 6 $/sec";
    
    
    while (true) {

    String input;
    try {

        Scanner stats = new  Scanner(System.in);

        input = stats.next();
        
        if(input.matches("stats")){ //if user inputs "stats", print stats
            System.out.println(statsString);
            
        } else if(input.matches("1") && money >= 50) { //if user inputs 1 and has 50+ money, buy one, subtract 50 from money and add 1 to money per second
       
            money = money - 50;
            mps = mps + 1;
            System.out.println(current money per second is " + mps);

        } else if(input.matches("3") && money >= 300) { //same as last comment, but different numbers
            
            money = money - 300;

每次 else if 语句中的一个起作用时，它不是每秒输出钱，而是每秒输出两次，然后如果另一个 else if 语句起作用，每秒输出三个钱……本质上，每秒的钱比每次增加更多每次我按 1-9 时，第二次。

现在，每次用户购买商品时都会启动一个新的计时器任务。如果您将任务计时器移到 while 循环上方，则可以确保只有一个计时器正在执行。

    static double money = 50;
    static double mps = 0; //money per second

    public static void main(String[] args) throws InterruptedException{


        System.out.println("\n*You have $50*"
                + "\n*Use this money to make more money*"
                + "\n*Type \"stats\" To see what you can buy*");

        String statsString = "*Type Numbers To Buy, You Can Only Buy If You Have Enough Money!*"
                + "\n1 = $50 = 1 $/sec"
                + "\n2 = $100 = 2.2 $/sec"
                + "\n3 = $300 = 7.2 $/sec"
                + "\n4 = $1,200 = 31.2 $/sec"
                + "\n5 = $6,000 = 168 $/sec"
                + "\n6 = $36,000 = 1,080 $/sec"
                + "\n7 = $253,000 = 5,060 $/sec"
                + "\n8 = $2,024,000 = 68,816 $/sec"
