java - 虽然循环条件未给出预期结果

Question

我正在编写斐波那契数列，除了我无法根据 while 条件(当输出 < maxOutput)限制输出之外，一切正常，无法将我的输出限制为用户输入的值。我的 while 条件在哪里出错了。请参阅下面的代码

import java.util.Scanner;

public class Fibonacci {

    private static int fib(int prev_Total, int current_Num) {
        return  current_Num + prev_Total; // return sum of the two
    }

    public static void main(String[] args){
        int f_Num, s_Num, maxOutput;

        Scanner maxNum = new Scanner(System.in);

        System.out.println("Enter the first value: ");
        f_Num = maxNum.nextInt(); 
        System.out.println("Enter the second value: ");
        s_Num = maxNum.nextInt(); 
        System.out.println("Enter the maximum value of the series: ");
        maxOutput = maxNum.nextInt(); 

        System.out.println(f_Num);  // print the first value by default 
        System.out.println(s_Num); // print the second value by default

        int prevTotal = f_Num; // initialise prevTotal
        int currentNum = s_Num; // initialise currentTotal
        int output = 0;  // initialise output

        while (output < maxOutput) {

            output = fib(currentNum, prevTotal); // assign the result of first two numbers added together to first output
            prevTotal = currentNum;  // update prevTotal (currentNum becomes our new prevTotal)
            currentNum = output;     // update currentNum (output becomes our new currentNum)
            System.out.println(output); // print output 

        }
    }
}

这应该有效:

while (true) {
    // assign the result of first two numbers added together to first output
    output = fib(currentNum, prevTotal);

    // update prevTotal (currentNum becomes our new prevTotal)
    prevTotal = currentNum;

    currentNum = output;
    if (output > maxOutput) {
        break;
    }
    // print output 
    System.out.println(output);
}
