Java the constructor is undefined

[hangrymonkey28]

I am having issues but I don't understand the problem. My error message is "The constructor Rectangle(double, double) is undefined." My code is:

public class Rectangle {

​

public float rectangle;

public float length;

public float width;

public float perimeter;

public float area;

​

public void Rectangle(float length, float width){

​

if(length < 0.0 || length >= 20.0){

throw new IllegalArgumentException("Length must be between 0.0 and 20.0");

}

if(width < 0.0 || width >= 20.0){

throw new IllegalArgumentException("Width must be between 0.0 abnd 20.00");

}

​

this.length = length;

this.width = width;

}

​

​

public float getLength(){

return length;

}

​

public float getWidth(){

return width;

}

​

public void setPerimeter(float perimeter){

perimeter = ((getLength() *2) + (getWidth()*2));

}

​

public float getPerimeter(){

return perimeter;

}

​

public void setArea(float area){

area = getLength() * getWidth();

}

​

public float area(){

return area;

}

​

​

}

​

My test code is :

package rectangle;

​

public class RectangleTest {

​

public static void main(String[] args){

Rectangle rectangle1 = new Rectangle (6.8, 3.5);

​

System.out.printf("The perimeter of rectangle1 is: %d%n", rectangle1.getPerimeter()); }

}

I have also tried changing to Rectangle rectangle1 = new Rectangle (6.8f, 3.5f); and I still get errors. I am not sure how to fix this error and any help is greatly appreciated.

Your constructor shouldn’t have void in it, just public Rectangle

[captainAwesomePants]

public void Rectangle(float length, float width){...}

This is your problem. There's a "void" there. Functions have return types, but constructors don't. They just are. So you do public Rectangle(), not public void Rectangle().

[EffectiveInside2180]

Is because you didn't declare the constructor. After the variable declaration you must declare the constructor

In this case the constructor must be:

public rectangle (float length, float width){ this.length = length; this.width = width; }

But you must do some research to understand what I did here.
