Description

Get maximum with three double parameters.

Demo Code

import java.util.Scanner;

public class Main 
{
   // obtain three floating-point values and determine maximum value
   public static void main(String[] args)
   {/*from  w w w.j  a va 2 s .  c  o  m*/
      // create Scanner for input from command window
      Scanner input = new Scanner(System.in);

      // prompt for and input three floating-point values
      System.out.print(
         "Enter three floating-point values separated by spaces: ");
      double number1 = input.nextDouble(); // read first double
      double number2 = input.nextDouble(); // read second double
      double number3 = input.nextDouble(); // read third double

      // determine the maximum value
      double result = maximum(number1, number2, number3); 

      // display maximum value 
      System.out.println("Maximum is: " + result); 
   } 

   // returns the maximum of its three double parameters
   public static double maximum(double x, double y, double z)
   {
      double maximumValue = x; // assume x is the largest to start

      // determine whether y is greater than maximumValue
      if (y > maximumValue)
         maximumValue = y; 

      // determine whether z is greater than maximumValue
      if (z > maximumValue)
         maximumValue = z;

      return maximumValue;
   } 
}
