3. Write a class named Calculator with static methods for
following operations
compute and return average of two parameterized integers
compute and return average of two parameterized doubles
multiply and return two parameterized integers
multiply and return two parameterized doubles
Solution
Calculator.java
public class Calculator {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int intAvg = average(5,5);
System.out.println(\"The average of two integers :
\"+intAvg);
double douAvg = average(5.5,5.5);
System.out.println(\"The average of two doubles :

\"+douAvg);
int intMul =multiply(5,5);
System.out.println(\"The multiply of two integers :
\"+intMul);
double douMul =multiply(5.5,5.5);
System.out.println(\"The multiply of two doubles :
\"+douMul);
}
public static int average(int a, int b){
return (a+b)/2;
}
public static double average(double a, double b){
return (a+b)/2;
}
public static int multiply (int a, int b){
return (a*b);
}
public static double multiply (double a, double b){
return (a*b);
}
}
Output:
The average of two integers : 5
The average of two doubles : 5.5
