I am having trouble figuring out why java is giving me an error for the symbols. I will post the errors below the code.
Java Code:
import java.util.Scanner;
public class ShelbyHarms_3_02 {
public static void main(String[] args) {
Scanner console = new Scanner(System.in);
double s = 0; //Semi-Perimeter
double x = 0; // Perimeter of triangle
double area = 0; //Area of triangle
double a, b, c = 0; //Input sides of triangle
//Input lengths of triangle
System.out.print("Please enter triangle side a: ");
a = console.nextDouble();
System.out.print("Please enter triangle side b: ");
b = console.nextDouble();
System.out.print("Please enter triangle side c: ");
c = console.nextDouble();
}
//Calculations for area and perimeter
public static double triangleArea (double a, double b, double c) {
s = (a + b + c)/2.0;
x = ((s) * (s-a) * (s-b) * (s-c));
area = Math.sqrt(x);
return area;
//Output the results
System.out.println("Your three triangle lengths are: " + '\n' + a +
'\n' + b + '\n' + c);
System.out.println("The area of your triangle is: " +
triangleArea(a, b, c));
} // End main()
} // End class
My errors are:
