I need JAVA CODE TO BE MODIFIED TO ACCOMPLISH AS PER THE INSTRUCTION BELOW:

Employee Class:

The Employee information you must track is as follows: • ID (This is generated randomly) • Name • Gender • Job Title • Organization they work for • Birthday As for the Organization that the Employee works for, you must also track this information: • Organization Name • Number of Employees of each organization Note: If an employee is added to a specific company, only the number of employees in that company is incremented by one, not the other.

Caller class:

You should be displaying a menu where the user can choose an action of the following: • Add Employee. • Remove Employee. • Update Employees Information: o Update the name. o Update the job title. o Update the workplace of an employee. • Print the number of employees: o In the whole system. o In Google only. o In Microsoft only. • Print employees' information: o Print the information of a single employee. o Print the information of all employees in the system. o Print the information of Google employees. o Print the information of Microsoft employees. Note: As a requirement for all inputs in your system, you must do error checking. For example, if the user to enter a whole number, nothing accepted but integers (NO characters, floating point numbers, or text of any kind), etc

 

//THE CODE BELOW WORKS FINE BUT PLEASE MODIFY IT FOR THE EMPLOYEE ID TO BE //GENERATED RANDOMLY
