Java: Please help with the following class. Thank you.

Here is the Class from Project 2 as mentioned in the instructions:

CLASS I NEED TO MODIFY:

* number of flight hours of the last flight rounded to the

* nearest int

*/

* default constructor setting

* name, current, destination to null capacity to 10 and

* creates the travelers array and sets size to capacity

*/

*/
