roll.java

JAVA编程思想源代码 值得一下 很难找的

package chapter6;

public class Roll {

	public static void main(String[] args) {

		int frequency[], face;
		frequency = new int[7];
		// 结果的概率
		for (int roll = 1; roll <= 6000; roll++) {
			face = 1 + (int) (Math.random() * 6);
			frequency[face]++;
		}

		for (int i = 1; i <= 6; i++)
			System.out.print("frequency(" + i + ") \t" + frequency[i] + "\n");
	}

}
