Exercice 1:
Question 1. Ecrire un méthode Java frequency qui travaille sur deux tableaux d'entiers t1 et 12 et
qui compte combien chaque élément de 12 est ré pété en tl et renvoie un tableau contenant le
résultat.
Question 2. Écrire un programme Java permettant:
• de déclarer explicitement les deux tableaux tl et t2.
• d'appeler la méthode frequency pour obtenir le tableau de fréquences F.
Exemple :
Si tl est :
-5
3
1
-6
3
7
-5
-6
3
-6
et 12 est:
-5
-6
7
Alors F sera:
4
la valeur 3 est répétée 4 fois, la valeur -5 est répétée 2 fois et ainsi de suite.

Question 2. Write a Java program that allows:
Declaring explicitly the two arrays tl and 12.
Calling the method frequency to obtain the array of frequencies
Еxample:
Iftl is:
3
-5
1
-6
3
-6
and 12 is:
-5
1
-6
Then Fwill be:
The value 3 is repeated 4 times; the value -5 is repeated 2 times, and so on.
