问题描述

我无法把随机数到阵列在我的测试类。在code是在java中。我不能这样做单独的，因为最终我将有多达600价值，填补了数组。下面是测试类：

I'm having trouble putting random numbers into the arrays in my test class. The code is in java. I can't do it individually, because eventually I'll have to fill the arrays with as many as 600 values. Here is the test class:

import java.util.Random;

public class test {
    /**
     * @param args
     */
    public static void main(String[] args) {
        int size = 1000;
        int max = 5000;
        int[] array = new int[size];
        int loop = 0;

        Random generator = new Random();
        //Write a loop that generates 1000 integers and
        //store them in the array using generator.nextInt(max)

        generator.nextInt(max); //generating one

        //I need to generate 1000
        //So I need some kind of loop that will generate 1000 numbers.
        for (int i =0; i<1000; i++)
        {
            generator.nextInt(max);
        }

        /**
         * After I do this, I'll have the array, array.
         * Then comes what's under this.
         * THat method is for measuring the time.
         * System.currentTimeMillis();,
         * with this, I can collect a time for the start of the method
         * and one for the end.
         * Time at the end, minus the time at the start
         * gets us the running time.
         */

        long result;

        long startTime = System.currentTimeMillis();
        sort.quickSort(array,  100,  array.length-1);

        long endTime = System.currentTimeMillis();
        result = endTime-startTime;

        System.out.println("The quick sort runtime is " + result + " miliseconds");

        long result2;

        long startTime2 = System.currentTimeMillis();
        sort.partition(array, 100, array.length-1);
        long endTime2 = System.currentTimeMillis();
        result2 =  endTime2 - startTime2;
        System.out.println("The partition runtime is "+result2 + " miliseconds");

        long result3;

        long startTime3 = System.currentTimeMillis();
        sort.bubbleSort(array, 100);
        long endTime3 = System.currentTimeMillis();
        result3 = endTime3-startTime3;
        System.out.println("The bubble sort runtime is "+result3 + " miliseconds");

        long result4;

        long startTime4 = System.currentTimeMillis();
        sort.selectionSort(array, 100); //change the second number to change
        //the size of an array.
        long endTime4 = System.currentTimeMillis();
        result4 = endTime4-startTime4;
        System.out.println("The selection sort runtime is "+result4 + " miliseconds");

    }
}

我已经通过测试类和它调用的函数另一类走了，没有错误。我只是需要把随机值放入数组莫名其妙。任何意见将是多少AP preciated。

I've already gone through the test class and the other class that it calls functions from, and there are no errors. I just need to put random values into the arrays somehow. Any advice would be much appreciated.

如果你看看在code，你可以看到，我已经做了一个小功能，用于生成数字本身。我只是不知道该怎么做，这样的数字将进入一个数组。

If you take a look at the code, you can see that I've already made a small function for generating the numbers themselves. I just don't know how to do that so that the numbers will go into an array.
