Java 我的阵营里发生了奇怪的事情

好的，我将展示我的代码，我的输入和输出，非常奇怪的是数组的值似乎从一行到下一行发生了变化

import java.io.*;

class chefAndNewRecipe 
{
public static void main(String[] args) throws IOException
{
    // TODO Auto-generated method stub
    BufferedReader r = new BufferedReader(new FileReader("/home/jer/Documents/chef.txt"));
    int testCases = Integer.parseInt(r.readLine());
    int numGuesses =0 ;

    for (int i=0; i<testCases; i++)
    {
        int ingredients = Integer.parseInt(r.readLine());

        String quantity = r.readLine();
        String arr[] = quantity.split(" ");
        int[] numIngredients = new int[arr.length];

        for (int j =0; j< ingredients; j++)
        {
            String temp = arr[i];
            numIngredients[i] = Integer.parseInt(temp);
            System.out.println("This is numIngredients index: " + j + " and value " +numIngredients[i]);//print array location and value
        }
        System.out.println("numIngredients[0]:" + numIngredients[0]); // should be 2 and is
        System.out.println("numIngredients[1]:" + numIngredients[1]); // should be 2 and is 0??
        for (int k = 0; k< numIngredients.length; k++)
        {   
            if (numIngredients[k] <2)
            {   
                System.out.println("Value of numIngredients[k]: " + numIngredients[k]);// print value of numIngredients
                System.out.println("-1");
            }
            else
            {   
                numGuesses += numIngredients[k];
            }

        }   
            System.out.println(numGuesses);
    }
}
}

import java.io.*；
chefAndNewRecipe类
{
公共静态void main（字符串[]args）引发IOException
{
//TODO自动生成的方法存根
BufferedReader r=新的BufferedReader（新的文件阅读器（“/home/jer/Documents/chef.txt”）；
int testCases=Integer.parseInt（r.readLine（））；
整数=0；
对于（int i=0；i即使对于循环变量，使用长变量名也很有用-您似乎在使用
i
而不是
j
：

for (int j = 0; j < arr.length; j++) // <== possibly arr.length is what you need.
{
    String temp = arr[j]; // <=== was i, same next line
    numIngredients[j] = Integer.parseInt(temp);
    System.out.println(
         "This is numIngredients index: " + j + //<== j this line
         " and value " + numIngredients[j]); // <== again, was using [i] 

}

for（int j=0；j
