Use the methods in the calling class to find the sum, average, maximum, and minimum of the array

package day02;


//主方法里面调用
public class ArrayCalc {
public static void main(String[] args) {
	int data [] = new int [] {12,22,33,44,55,66};  //初始化数组
	System.out.println(arrayUnit.ArrayClal(data));
	

}
}

package day02;

//定义arrayUnit类进行数组的求和、平均值、最大值、最小值的计算
public class arrayUnit {
public static String  ArrayClal(int data [] ) {
	double sum=0;   //总和
    double avg = 0.0;   //平均值
    double max = data[0];
    double min=data[data.length-1];
        for(int i = 0; i<data.length;i++) {
	        sum+=data[i];
            avg=sum/data.length;
            avg=(double) Math.round(avg * 100) / 100;   //小数点后面保存两位四舍五入
                if(max<data[i]) {
	               max=data[i];
            }   else {
                	min=data[i];
            }

}
        return "数组的总和为:"+sum+"，平均值为:"+avg+"，最大值为:"+max+"，最小值为"+min;
}
