jshell> class Employee {

...> public Employee(String firstName, String lastName, String designation) {
...> this.firstName = firstName;
...> this.lastName = lastName;
...> this.designation = designation;
...> }
...> public String getFirstName() {
...> return firstName;
...> }
...> public String getLastName() {
...> return lastName;
...> }
...> public String getDesignation() {
