Constructors vs Methods
Following are the difference between Constructors and Methods
| Java Constructor | Java Method |
| Constructor is used to initialize the state of an object. | Method is used to expose behaviour of an object. |
| Constructor must not have return type. | Method must have return type. |
| Constructor is invoked implicitly. | Method is invoked explicitly. |
| Compiler provides a default constructor if you don’t have any constructor. | Method is not provided by compiler in any case. |
| Constructor name must be same as the class name. | Method name may or may not be same as class name. |

private int eid;
public Employee() {
