Create a class Rectangle.The class has attributes length   and width,each of which defaults to 1.It has methods that calculate the premiter and the area of the rectangle.It has set and get methods for both length and width.The set method should verify that length  and width are each floating-point numbers larger than 0.0 and less   than 20.0 .(Fille must be save as : Assignment3.java)

import javax.swing.JOptionPane;
class SetValue
{
            float l,w,a;
            SetValue()
            {
                        w=1;
                        l=1;

            void set()
            {
                        String s;
                        s=JOptionPane.showInputDialog("Length = ");
                        a=Float.parseFloat(s);
                        if(a<20&&a>0)
