java - 而“!b.equals(x)|| !b.equals(y)”是一个无限循环？

大家好，这是我的代码，它正在做一个循环，但是它要做的是，如果用户键入借款，它将询问用户它做了多少，但是他们键入一个数字，它将再次询问他们您想借还是卖，这是一个无限循环。

case 3:
            do{
                System.out.println("What would you like to do? Please type borrow to borrow money or sell to sell assets: ");
                    b = scan.nextLine().toLowerCase();
                if(b.equals("borrow")){
                    System.out.print("how much would you like to borrow Remmber if you go over 50000 debt its game over.");
                    try {
                        input = scan.nextInt();
                    } catch (Exception e) {
                        System.err.println("That is not a number!!");
                    }
                    account.setdebt(account.getDebt() + input);
                    account.setBalance(account.getBalance() + input);
                    System.out.println("Your new Balance is " + account.getBalance());
                }
                else if(b.equals("sell")){
                    sellA();
                }else{
                    System.out.println("You didn't input 'borrow' or 'sell'. Reinput please");
                }
            }while(!b.equals("borrow") || !b.equals("sell"));
            break;

最佳答案

您需要在||内部将&&更改为while，否则条件始终为true。 b不等于的那两个值中至少会有一个。
