    private double side = 0; 
    String color; /*from ww  w.  j  a v a2s.c  o  m*/
    public MyClass (double length){ 
        this.side = length; 
     } 
    public double getSide ()  {  return side;     } 

    public void setSide (double side)  {  this.side = side;    } 
     
} 

public class Main  { 
    public static void main (String [] args) throws Exception  { 
        MyClass mysq = new MyClass (10); 
        mysq.color = "red"; 
         
        //set mysq's side to 20 
     } 
}

Which of the following statements will set mysq's side to 20?

B. mysq = new MyClass (20); 
C. mysq.setSide (20);
