Java Programming The Orlando Park District holds a miniOlymp

Java Programming:

The Orlando Park District holds a mini-Olympics each summer.

Create a class named Contestants with fields for a name, age, and street address.

Include code to check that the age of the contestant cannot be over 18 and under 14

                If invalid make user enter new age.

Include a constructor that assigns parameter values to each field and a toString() method that returns a String containg all values.

Include an equals() method that determines two Contestants are equal if they have the same values in all three fields.

Create a child class called Event that has a field for eventType and a message containing the type of event.

Create an application with two arrays of at least eight Contestants each

                one holds Contestants in the 100 meter dash, and the other holds Contestants in the high-jump competition.

Prompt the user for contestant values, only allow the two types of events.

After the data values are entered, display all values for Participants who are in both events.

Save files as Contestant.java, Event.java and TwoEventParticipants.java

//Prompt the user for contestant values, only allow the two types of events.
System.out.println(\"Enter dash Contestants: \");
