JAVA HELP

can't figure out why this doesnt return the perimeter

public class Triangle
{
private double side1;

public Triangle(double side1, double side2, double side3)
{
if (side1 <= 0 || side2 <= 0 || side3 <= 0)
{
System.exit(0);
}
}

public double getPerimeter (double side1, double side2, double side3 )
{
double Perimeter = side1 + side2 + side3;
return Perimeter;
}

Answer 1

public static void main(String[] args)
{
Triangle t = new Triangle(3,4,5);
t.getPerimeter(3,4,5);

}
}

Answer 2

I would first like to point out that you are not using a class to its potential. Your side variables, with the exception of your side1, are all local variables and are not accessible after the method closes.

Answer 3

From what you've posted, you can't determine if a perimeter is being returned. Try changing the second line of main to:

System.out.println( t.getPerimeter(3,4,5) );

Answer 4

@rsmith6559 is correct, the perimeter IS being returned, you are just neglecting to display the results.
