Need to : - declare enum attribute (year & country) - implement enum with constructor (two parameters in header)
- appropriate public methods to access private attribute
- Input file(Disease type , person age, person name)
- Need another classnamed as Person
import java.util.*;
import java.io.*;
enum Disease{MALARIA(1990,"Italy"), COVID(2020,"China"), DENGGI(2013,"Malaysia");
private int year;
private String country;
private Disease(int y, String c){
year=y;
country=c;
}
public int getYear(){
return year;}
public String getCountry(){
return country;
}
public void print(){
System.out.println("Year: "+ year +" "+"Country: "+ country);
}
}

private int pAge;
private String name;
Person(int pAge, String name){
this.pAge=pAge;
this.name=name;
}
public int getAge(){
return pAge;
}
public void print(){
System.out.println("Age: " + pAge + "Name: " + name);
}
}
public class TestDisease{
public static void main(String args[]) throws FileNotFoundException{
