Question

用Java实现求以下数值的平均值然后开方：int1 = 5； int2 = 7 ；int3 = 4； int4 = 25 ；int5 = 13 。

要求输出为：average of numbers is 10.8
square root of average is 3.286335345030997
初学者不太懂，谢谢！

Answer 1

public class Avg {

/**
* @param args
*/
public static void main(String[] args) {

int int1 = 5;
int int2 = 7;
int int3 = 4;
int int4 = 25;
int int5 = 13;

double averge = (double)(int1 + int2 + int3 + int4 + int5) / 5;
double sqrt = Math.sqrt(averge);
System.out.println("average of numbers is " + averge);
System.out.println("square root of average is " + sqrt);
}

}

Answer 2

double avg=(double)(int1+int2+int3+int4+int5)/5;
System.out.println("average of numbers is "+avg);
System.out.println("square root of average is " +Math.sqrt(avg));
