Question
he Cullerton Park District holds a mini-Olympics each summer. Create a class named Participant with fields for a name, age, and street address. Include a constructor that assigns parameter values to each field and a toString() method that returns a String containing all the values. Also include an equals() method that determines two participants are equal if they have the same values in all three fields. Create an application with two arrays of at least eight participants each—one holds participants in the mini-marathon, and the other holds participants in the diving competition. Prompt the user for participant values. After the data values are entered, display values for participants who are in both events.
Note: This is in Java
Explanation / Answer
Participant.java
public class Participant {
//Declaring instance variables
private String name;
private int age;
private String address;
//Parameterized constructor
public Participant(String name, int age, String address) {
this.name = name;
this.age = age;
this.address = address;
}
// getters and setters
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
//This method compares two Participant Objects
public boolean equals(Participant other) {
if (address == null) {
if (other.address != null)
return false;
} else if (!address.equals(other.address))
return false;
if (age != other.age)
return false;
if (name == null) {
if (other.name != null)
return false;
} else if (!name.equals(other.name))
return false;
return true;
}
//toString method is used to display the contents of an object inside it
@Override
public String toString() {
return "Participant [name=" + name + ", age=" + age + ", address="
+ address + "]";
}
}
