egg jam ple chai..
java ma dim hoi..c++ teti aunna..Object Oriented ko concept nai bujhne ta honi..hoina?
set ra get method chai afai bujha hoi..alchi lago ke...
public class Saman
  {

     String samanName;
      int samanQty;
     
      /**regular constructor**/   
      public Saman(String sName, String sQty)
       {
           samanName = sName;
           samanQty = sQty;
        }
      
     /** copy constructor **/
     public Saman(Saman s)      /** copy constructor always takes Class Object as parameter
    {
        this.samanName = s.getSamanName();
        this.samanQty = s.getSamanQty();
       /** Alternate methods
         * Call regular constructor
         * return(Saman (s.getSamanName(),s.getSamanQty());
      }

       public void testCopyConstruct()
     {
         Saman chauChau1 = new Saman("waiwai",10);  //calling regular constructor
         Saman chauChau2 = new(chauChau1); //this will copy all the attributes of chauchau1       
                                                                     //to                      chauchau 2
         chauChau2.setSamanName("rara"); //aba rara ni 10 wotai raicha bhane..kina feri 10 bhanera
                                                                //initialize garnu bhanera...tyo copy use garya hoi
