Hello,
I tried to this in the beginning :
public static void haveFun(Person person) {
if(person instanceof Player)
{
person.play();
}
else if(person instanceof Dancer)
{
person.dance();
}public static void haveFun(Person person) {
if(person instanceof Player)
{
Player.play();
}
else if(person instanceof Dancer)
{
Dancer.dance();
}package fr.codegym.task.task14.task1407;
import java.io.BufferedReader;
import java.io.InputStreamReader;
/*
Joueur et danseur
*/
public class Solution {
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
Person person = null;
String key;
while (!(key = reader.readLine()).equals("quitter")) {
if ("joueur".equals(key)) {
person = new Player();
} else if ("danseur".equals(key)) {
person = new Dancer();
}
haveFun(person);
}
}
public static void haveFun(Person person) {
if(person instanceof Player)
{
Player.play();
}
else if(person instanceof Dancer)
{
Dancer.dance();
}
}
interface Person {
}
static class Player implements Person {
void play() {
System.out.println("joue");
}
}
static class Dancer implements Person {
void dance() {
System.out.println("danse");
}
}
}
