Initializing variables using constructors

Constructors are used to initializing the variables. Following example helps in better understanding.

Code:

---

public class Lab {
private int id;
private String name;
private String category;
private Date dateOfConst;

public Lab(int id, String name, String category, Date dateOfConst)
{
        this.id = id;
        this.name = name;
        this.category = category;
        this.dateOfConst = dateOfConst;
        }

}
