java储存数组并输出平均值 java数组平均值怎么求

package edu.cdu.ppj.experiment3;

public class arr {

	public static void main(String[] args) {

		int[] data = { 12, 23, 456, 222, 768, 93245 };
		int sum = 0;
		double average = 0.0;
		for (int i = 0; i < data.length; i++) {
			sum += data[i];
		}
		System.out.println("和是 " + sum);
		average = sum / data.length;
		System.out.println("平均值是 " + average);
	}
}

效果图：
