求取数组的总和和平均值

public class 取得数组总和 {

	public static void main(String[] args) {
		int[] data= {12,43,8,9,1,46,32,23,65,78,1,1};
        double s=0;
        for(int x=0;x<data.length;x++) {
        	s=s+data[x];
        }
        System.out.println(s);
	}
}

public class 取得数组总和平均值 {

	public static void main(String[] args) {
		int[] data= {12,43,8,9,1,46,32,23,65,78,1,1};
        double s=0;
        for(int x=0;x<data.length;x++) {
        	s=s+data[x];
        }
        System.out.println(s/data.length);
	}
