ecco che cosa ho combinato io... 

code:

Vendemmia miaVendemmia = new Vendemmia();
Vendemmia tuaVendemmia = new Vendemmia(200);
miaVendemmia.carica(100);
miaVendemmia.pigia(70);
tuaVendemmia.pigia(80);
miaVendemmia.carica(50);
miaVendemmia.pigia(90);

System.out.println(miaVendemmia);
             Vendemmia: 50
             Mosto: 40,5

Vendemmia.getPigiature(); 3
Vendemmia.getMosto(); 61,2
Vendemmia.getCarico(); 350

questo è il primo esercizio... la cosa che mi rende perplesso è:

nella dichiarazione del metodo carica la prof mi pare che abbia messo

public int carica(int carica)
quando si richiama quel metodo bisogna assegnarlo a qualkosa? tipo

t = miaVendemmia.carica();
dato che dava un valore int di ritorno...

ho trovato un altro foglio con gli esercizi che ho fatto stamane...
l'esercizio sui random io l'ho fatto cosi

il range di valori
-9 +9
0 3

poi tra -2 e 4 con il metodo random

rand.nextInt() %3 +1

tra 4 e 12 con math
Math.random() * 8 +4

johnnyd mi sa che hai sbagliato, rand.nextInt() %3 +1 ti da' un range da -1 a 3 e Math.random()*8 + 4 da 4 a 11. Per il metodo andava bene così com'è senza assegnarlo a niente.
