java - 得到运行总数？

Question

我拼命地试图让我的代码的最后一列将所有中间列的数字加起来。但它似乎已经从 1 开始了。

另外，一个附带问题：当我输入 12 时，我得到 11 个结果，因为“y”从 1 开始。有没有办法在循环中解决这个问题？

import javax.swing.JOptionPane;
public class Project
    {
    public static void main( String[] args )
        {
        String input = JOptionPane.showInputDialog( "How many Fibonacci numbers 
                                                     do you wish to see?" +
                                                     "\n" + "Choose 1-50!");

        int numFib = Integer.parseInt( input );
        int numbers[] = new int[numFib];
        int fibonacci[] = new int[50];

        for( int index = 1; index < numbers.length; index++ )
            {
            numbers[index] = index;
            }
        for( int x = 0; x < numbers.length; x++ )
            {
            if( x == 0 )
                {
                fibonacci[0] = 0;
                }
            if( x == 1 )
                {
                fibonacci[1] = 1;
                }
            if( x > 1 )
                {
                fibonacci[x] = fibonacci[x-2] + fibonacci[x-1];
                }
            }
        System.out.println( "Number" + "\t" + "Fibonacci Number" + "\t" + 
                                              "Running Total of FNs" );
        for( int y = 1; y < numbers.length; y++ )
            { 
            int total = fibonacci[y] + fibonacci[y - 1];

            System.out.println( numbers[y] + "\t" + fibonacci[y - 1] 
                                + "\t" + "\t" + "\t" + total );
            }
        }
    }

Answer 1

从零开始：

int total = 0;
for( int y = 0; y < numbers.length; y++ )
{ 
   total += fibonacci[y];

   System.out.println( numbers[y] + "\t" + fibonacci[y] 
                                + "\t" + "\t" + "\t" + total );
}

total -= fibonacci[0] + fibonacci[numbers.length-1];
