art*_*emd 1 java arrays random
我有一个问题,我试图用一个主方法和一个名为LOAD()的方法来填充1-300范围内的30个随机整数.出于某种原因,我的代码生成了一个包含我的测试语句的数组,System.out.println("Here are 30 random numbers: " + Arrays.toString(randomThirty));但它只填充了0并且在所有字段中都没有其他数字.
import java.util.*;
public class randArray
{
public static void main(String args[])
{
//main method which creates an array to store 30 integers
int[] randomThirty = new int[30]; //declare and set the array randomThirty to have 30 elements as int type
System.out.println("Here are 30 random numbers: " + Arrays.toString(randomThirty));
LOAD(randomThirty); // the job of this method is to populate this array with 30 integers in the range of 1 through 300.
}
public static void LOAD(int[] randomThirty)
{
// looping through to assign random values from 1 - 300
for (int i = 0; i < randomThirty.length; i++) {
randomThirty[i] = (int)(Math.random() * 301);
}
}
}
