Java PreTest 1 Exercise

 Enum type Disease : MALARIA(1990,”ITALY”)
 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);
}
}

class Person{
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{

//creating File instance to reference text file in Jaca
File text= new File("C://JavaPrograms//dataDisease.txt");
int i=0;
String type, name;
int age;
ArrayList<Disease> dList= new ArrayList<Disease>();
ArrayList<Person> pList= new ArrayList<Person>();

//Creating Scanner instance to read File in Java
Scanner input = new Scanner(text);
while(input.hasNext()){
type=input.next();
age=input.nextInt();
name=input.nextLine();

Disease dis=Enum.valueOf(Disease.class,type.toUpperCase());
dList.add(dis);
Person dataP= new Person(age,name);
pList.add(dataP);
}
System.out.println("--------------------------------");
    for(Disease ds: dList)
          ds.print();
System.out.println("--------------------------------");
    for(Person ps: pList)
          ps.print();
}//main
}//TestDisease
