Java Syntax Error

Question

What is wrong with my code? I have an error concerning the scanner part of it. I have to add "more details be4 I can post this question, so this is it.

import java.util.Scanner
class rectangle
{
  double width;
  double length;
  double findArea(double a, double b)
  {
    width=a;
    length=b;
    return a*b;
  }
}
public class area
{
  public static void main(String args[])
  {
    {
      System.out.println("Enter the dimensions of the square.");
      Scanner x = new Scanner(System.in);
      Scanner y = new Scanner(System.in);
    }
    {
      rectangle objrect = new rectangle();
      System.out.println(objrect.findArea(x, y));
    }
  }
}

1) Always copy/paste error & exception output. 2) Please use the correct spelling for words like 'you', 'your' & 'please'. This makes it easier for people to understand and help. 3) Please learn common Java naming conventions (specifically the case used for the names) for class, method & attribute names & use them consistently. — Andrew Thompson

You are passing two Scanner objects to a method findArea that expects two double values; that won't work. You should have one Scanner object, with which you should be able to obtain double values that you can pass in to the findArea method.

Replace the x and y value input line with follows:

Scanner s = new Scanner(System.in);
double x = s.nextDouble();
double y = s.nextDouble();

Now call the method finaArea as follows:

objrect.findArea(x, y)
