java - 数字模式截止

Question

public class numPattern {
    public static void main(String[] args) {
        int digit1 = 2;
        int digit2 = 7;
        int    tal = 0;

        System.out.print(digit1 + " ");
        System.out.print(digit2 + " ");

        while (tal < 550) {
            tal = digit1 + digit2;

            System.out.print(tal + " ");

            digit1 = digit2;
            digit2 = tal;
        }
    }
}

这输出 2, 7, 9, 16, 25, 41, 66......453 和 733

问题是它应该在 453 处停止，因为 733 远远超过 550。

什么命令可以确保程序在 453 处结束以满足我要寻找的大于或等于 550 的值？

Answer 1

在while中增加tal的值:

    int digit1 = 2;
    int digit2 = 7;
    int tal = 0;

    System.out.print(digit1 + " ");
    System.out.print(digit2 + " ");

    while((tal = digit1 + digit2)< 550)
    {

        System.out.print(tal + " ");

        digit1 = digit2;
        digit2 = tal;
    }
