Salutations. This is my first post. Glad to be here.
I have a question for a
java developer whom may be willing to assist a newbie in need of aid?
Like many of you i'm attempting to teach myself Java. I have been reading tutorials and reading on the messageboard and thank you for your interesting advice as of yet.
My question: I have just developed a small program to calculate the perimeter and area of a rectangle. What i'm trying to do is create seperate methods for each of several functions I want to implement.
my code:
import javax.swing.*; //imports java swing to implement msgbox
public class rectangle //creates class rectangle
{
public static void main (
String[] args) //beginning of code
{
String a1, a2, output;
double area, perimeter, length, width;
a1 = JOptionPane.showInputDialog("Enter length");
a2 = JOptionPane.showInputDialog("Enter width");
length = Double.parseDouble(a1);
width = Double.parseDouble(a2);
area = length * width;
perimeter = (length * 2) + (width * 2);
output = "The length of the rectangle is " + length + " and the width is " + width + " Therefore; The area is " + area + " and the perimeter is " + perimeter;
JOptionPane.showMessageDialog(null, output, "rectangle logic",
JOptionPane.INFORMATION_MESSAGE);
System.exit(0);
}
}
As you can see my code works fine. However; I was wondering if anyone could help me break down my sections into seperate methods? IE: have a method for perimeter() (would define required calculation for perimeter), area() (would define required calculation for area), getData() (which would display calculation)
Basically I think I have someone of a solid understanding in terms of basic coding; however I have no idea how to implement methods. If someone could help me implement methods into this small program i'd be very greatful.
I look forward to anyone willing to assist me in my everexpansive quest for knowledge.
