Java - 扫描仪不要求输入

Question

System.out.println("Please enter the amount of money you have here: ");
Scanner have = new Scanner(System.in);
System.out.println("Please enter your starting bet here: ");
Scanner rate = new Scanner(System.in);

int moneyHad = Integer.parseInt(have.next());
int moneyRate = Integer.parseInt(rate.next());
System.out.println(moneyHad + ", " + moneyRate);

这是我的代码，这是我的输出。

Please enter the amount of money you have here: 
Please enter your starting bet here: 1
1
1, 1

如您所见，它会在询问之前将它们打印出来，这就是输出的第 1 行没有输入的原因。

请快帮帮我!

Answer 1

• 无需创建 2 个 Scanner 对象
• 有一个方法返回 int ( scanner.nextInt() ) 不需要 ParseInt
• 当您调用 scanner.nextInt() 时输入为红色，而不是在创建扫描器对象时

试试这个:

Scanner scanner = new Scanner(System.in);

        System.out.print("Please enter the amount of money you have here: ");
        int moneyHad = scanner.nextInt();
        System.out.print("Please enter your starting bet here: ");
        int moneyRate = scanner.nextInt();


        System.out.println(moneyHad + ", " + moneyRate);
