为什么我没有跳出循环？ 即使我的输入是正确的

Question

public void getLogin()throws IOException{ int x=1;

    do {
        try {
            data.put(961668 , 2255);
            data.put(961768 , 2253);
            data.put(961568 , 2353);

            System.out.println("----------Welcome to the ATM Machine Project----------");
            
            System.out.println("Enter your Account number: ");
            setAccountNumber(menuOutput.nextInt());
            
            System.out.println("Enter your correct PIN number: ");
            setPinNumber(menuOutput.nextInt());
        
        }catch (Exception e) {
            System.out.println("\n"+"You have Enter Incorrect value !! you have to enter only numbers: "+"\n");
            x=2;
        }
        for(Entry<Integer, Integer> entry : data.entrySet()) {
            if(entry.getKey()== getAccountNumber() && entry.getValue()== getPinNumber()) {
                getAccountType();
            }
        }
        System.out.println("\n"+"Wrong Account or Pin Number "+"\n");
    }while(x == 1);
}

Is there any reason, performance or otherwise, to prefer one over the other? Where am I doing Mistake? I check every thing.

Answer 1

The do loop executes as long as the value of x is 1. Which in your case is not changed even when the desired result is achieved.

May be try updating the value of x to some other value except 1 in valid scenario as well.
