28. Write a Java program to create a class called Rectangle with private instance variables length and width. Provide public getter and setter methods to access and modify these variables.

            class Rectangle{
                private double length, breadth;
                
                public void setLength(double l){
                    length = l;
                }
                public void setBreadth(double b){
                    breadth = b;
                }
                public double getLength(){
                    return length;
                }
                public double getBreadth(){
                    return breadth;
                }
            }
            
            class Main{
                public static void main(String[] args){
                    Rectangle b1 = new Rectangle();
                    b1.setLength(10.3);
                    b1.setBreadth(18.38);
                    System.out.println("Length : " + b1.getLength());
                    System.out.println("Breadth : " + b1.getBreadth());
            
                }
            }
        

OUTPUT

            Length : 10.3
            Breadth : 18.38
