Rectangle values won't print

Question

I am working on a program to create a rectangle class with attributes of length and width both set to 1 and then caculate the area and the perimeter but it won't display the data. and gives me an error on the line for printing area and perimeter say it needs method but the method is already there. any help would be appreciated.
package rectangle;
import java.util.*;
import java.awt.Rectangle;
public class rectangle {
    private double length;
    private double width;
    private double area;
    private double perimeter;
    /** Creates a new instance of rectangle */
    public rectangle() {
    public static void main(String[] args) {
        public void setWidth(double x)
        width = (x > 0.0 && x < 20.0)?x : 1;       
    public void setLength(double y)
        length = (y > 0.0 && y < 20.0)?y : 1;
    public double getWidth()
    return width;
    public double getLength()
        return length;
    public double cArea() {
    return length * width;
    public double cPerimeter( ) {
    return (2 * length) + (2 * width);
      // Print out of rectangle details
     public void showDetails()
       System.out.println("Rectangle Width: " + width);
       System.out.println("Rectangle Length: " + length);
       System.out.println("Rectangle Perimeter: " + cperimeter());
       System.out.println("Rectangle Area: " + carea() + "\n");
     } // end class main   
}  // end class Rectangle

I am no longer getting an error but it still does not display informationany help would be appreciated. reposting code without error.
package rectangle;
import java.util.*;
import java.awt.Rectangle;
public class rectangle {
    private double length;
    private double width;
    private double area;
    private double perimeter;
    /** Creates a new instance of rectangle */
    public rectangle() {
    public static void main(String[] args) {
        public void setWidth(double x)
        width = (x > 0.0 && x < 20.0)?x : 1;       
    public void setLength(double y)
        length = (y > 0.0 && y < 20.0)?y : 1;
    public double getWidth()
    return width;
    public double getLength()
        return length;
    public double Area() {
    return length * width;
    public double Perimeter( ) {
    return (2 * length) + (2 * width);
      // Print out of rectangle details
     public void showDetails()
       System.out.println("Rectangle Width: " + width);
       System.out.println("Rectangle Length: " + length);
       System.out.println("Rectangle Perimeter: " + Perimeter());
       System.out.println("Rectangle Area: " + Area() + "\n");
     } // end class main   
}  // end class Rectangle
output should be 
width = 1
length = 1
area = results of width * length
perimeter = 2 * width + length * 2
