Simplify setter and getter of java class

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!
