I am trying to verify my understanding on setter and getter on java class with this example:
Code:
//MaximumFinder2.java
import java.util.Scanner;
public class MaximumFinder2
{
public static void main (String[] args)
{
Scanner input = new Scanner(System.in);
System.out.print("Enter three floating numbers separated by spaces: ");
double num1 = input.nextDouble();
double num2 = input.nextDouble();
double num3 = input.nextDouble();
maximum max = new maximum(num1, num2, num3);
System.out.println(max.getMaximum(num1, num2, num3));
} //end of main()
} //end of class Maximum Finder2
and the maximum class
Code:
//maximum.java
public class maximum
{
private double maximumValue;
// public double a, b, c;
maximum(double a, double b, double c)
{
this.maximumValue = getMaximum(a, b, c);
}
public double getMaximum (double a, double b, double c)
{
return setMaximum (a, b, c);
}
public double setMaximum (double x, double y, double z)
{
double maxVal = x;
if (y > maxVal)
maxVal = y;
if (z > maxVal)
maxVal = z;
return maxVal;
}
} //end of maximum class
The code is working, but I am not sure how to simplify the code for all those local variables: double a, b, c and double x, y, z. I tried using global version of them, which was commented out, to make the class simpler, but did not work. Are those local variables necessary to make the maximum class?
Thanks a lot!

Hi,
Is it possible to call the constructur of a java class in a shell script?
I know you can call static methods, but can you also call the constructor?
