Test the functionalities using the provided Tester class. 

 

Sample Input and Output

 

Hint:  For round-off to two decimal digits:

double num1 = 65, num2 = 175;
double num3 = num1/num2;
System.out.println(Math.round(num3*100.0)/100.0);

class Calculator{

public double findAverage(int number1,int number2,int number3){

double sum=(number1+number2+number3);

double average=sum/3;

double roundoff=Math.round(average*100.0)/100.0;

return roundoff;

}

}

class Tester{

public static void main(String args[]){

Calculator calculator= new Calculator();

double x=calculator.findAverage(12,8,15);

System.out.println(x);
