java 这个代码不错

import java.util.Random;
public class RandomTest
{
public static void main(String[] args)
{
int[] array = new int[41];
Random random = new Random();
for(int i = 0; i < 50; i++)
{
int number = random.nextInt(41) + 10;
array[number - 10]++;
}
for(int i = 0; i < array.length; i++)
{
if(0 == array[i])
{
continue;
}
System.out.println(i + 10 +"出现了" + array[i] + "次");
}

}
}
