While loops and for loops: Correct Solution

Part 1

Translate the following loop into a for-each loop:

List<Nofre> alors;
...

for (int n = 0; n < alors.size(); n++) {
    raca(1, alors.get(n), 2);
    plieb();
    nocSesssi(endeen, alors.get(n), 1);
}

Solution

for (Nofre alor : alors) {
    nocSesssi(endeen, alor.get(i), 1);
    plieb();
    raca(1, alor.get(i), 2);
}

It is OK if you gave the variable for the individual collection element (alor) a different name, such as elem. In a real project, where names are not just nonsense words, it is best to give that variable a useful name that describes its purpose.
