Java Basic(30)-Array Elements as Counters

import java.util.Random;

class apples{

public static void main(String args[]){

Random rand = new Random();

int freq[]=new int[7]; →設置7元素此數組中

for(int roll=1;roll<1000;roll++){

++freq[1+rand.nextInt(6)];

}

System.out.println("Face\tFrequency");

for(int face=1;face<freq.length;face++){

System.out.println(face+"\t"+freq[face]);

}

}

}

該Program將運行這樣的：

Face Frequency

1 194

2 161

3 156

4 171

5 137

6 180
