斐波那契数列 java

Question

我已经生成了一个程序来计算斐波那契数列，其限制由用户通过键盘给出，但是我遇到了一个问题，因为我已经要求该数列从 1 开始，而不是像我所做的那样从 0 开始。我怎样才能做到这一点？我的斐波那契数列显示我从 1 而不是从 0？

     int maxNumber = 0; 

     int previousNumber = 0;

     int nextNumber = 1;

        System.out.println("How many numbers you want in Fibonacci:");

        Scanner scanner = new Scanner(System.in);

        maxNumber = scanner.nextInt();

        System.out.print("Fibonacci Series of "+maxNumber+" numbers:");

        for (int i = 1; i <= maxNumber; ++i)

        {

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

            int sum = previousNumber + nextNumber;

            previousNumber = nextNumber;

            nextNumber = sum;

        }

Answer 1

只需做一个简单的更改并在计算后打印数字。for (int i = 1; i <= maxNumber; ++i)&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// System.out.print(previousNumber+" ");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; int sum = previousNumber + nextNumber;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; previousNumber = nextNumber;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; nextNumber = sum;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.print(previousNumber+" ");&nbsp; &nbsp; &nbsp; &nbsp; }

Answer 2

使用int previousNumber = 1;，它将从 1 开始。
