Howdie Partners:

I have the following code and get ye olde ';' Exception error.

Please help me!

import javax.swing.JOptionPane;
import java.util.Scanner;
public class Triangle
public static void main (String [] args)
double num1, num2, num3; // input values
double total, perimeter;
//get side lengths
Scanner rdr = new Scanner(;

// Define perimeter
perimeter = (num1 + num2 + num3);

// Input the two numbers
System.out.println("Input your first number.");
num1 = console.nextDouble();

System.out.println("Input your second number.");
int num2 = console.nextDouble();

System.out.println("Input your third number.");
int num3 = console.nextDouble();

// Determine the total of the first two numbers
int total = (num1 + num2);
int answer = Integer.parseInt(triangle);

If (answer)
(total > num3 = true);
System.out.print("The perimeter is " + perimeter);

Else (answer)
(total < num3 = false);
System.out.print("The data is incorrect.");

// Show output in a dialogue box
Thank you.

Very humbly yours,

Java is case sensitive and all keywords are lower case.

Welcome to the Ranch, Michelle. Please give more details of the errors you are getting; I am pretty sure (as Joanne has hinted) that your code as shown won't compile or run so you can get an Exception. If quoting code, please use ctrl-C ctrl-V and don't copy it by hand, in case you introduce yet more errors.
I agree. Here's the link:
