Write a program with a main method and two other methods.
1.Main Method:
-User enters three numbers
-Print out all results
2.calcSum Method (first, second, third):
- Get three numbers as parameters
- if first is less than second, first = first * second ¥ if second is less than third, third = second * first
- Return the sum of these three numbers ¥ calcAvg Method (first, second, third):
- Get three numbers as an input ¥ Return the average of these three numbers as double value
Output:
Enter first number:3
Enter second number:5
Enter third number:7
The summation of all numbers: 95
The average of all numbers: 5.0
Explanation / Answer
package average;
import java.util.Scanner;

return (num1 + num2 + num3);

int num1 = input.nextInt();
System.out.println("Enter number 2 :");
int num2 = input.nextInt();
System.out.println("Enter number 3 :");
int num3 = input.nextInt();
System.out.println("The summation of all numbers: "+calcSum(num1, num2, num3));
System.out.println("The average of all numbers: "+Summation.calcAvg(num1,num2,num3));
}
