试图分类数组

这是我的问题：我想计时程序需要多长时间来对数组进行分类。之后我尝试打印结果，但它打印出一个0。这是我的主要方法：

   public static void main(String[] args) {
       
       for ( int b = 0; b < array1.length; b++) {
          int n = (int)(Integer.MAX_VALUE * Math.random());
          array1[b] = n;
          array2[b] = n;
        }//end of for loop
       
       long startTime = System.currentTimeMillis();
       insertionSort(array1);
       long runTime = System.currentTimeMillis() - startTime;
       System.out.println("The runtime of the sorting is "+ runTime);

   
    }//end of main

这是我的输出：

The runtime of the sorting is 0

预先感谢！

Here's my question: I want to time how long the program takes to sort an array. I try to print the result afterward, but it prints out a 0. Here's my main method:

   public static void main(String[] args) {
       
       for ( int b = 0; b < array1.length; b++) {
          int n = (int)(Integer.MAX_VALUE * Math.random());
          array1[b] = n;
          array2[b] = n;
        }//end of for loop
       
       long startTime = System.currentTimeMillis();
       insertionSort(array1);
       long runTime = System.currentTimeMillis() - startTime;
       System.out.println("The runtime of the sorting is "+ runTime);

   
    }//end of main

And here's my output:
