Hi Friend,

If there is a need to to refer to instance of the class from its method,then you can use this keyword.It avoids name confliction.

this.matricNo=matricNo;
this.name=name;
this.date=date;
this.gender=gender;

In the above code this.matricNo,this.name,this.date,this.gender refers to the instance variable matricNo,name,date,gender respectively.While matricNo,name,date,gender also refers to arguments passed to the constructor.

Thanks
