While loops and for loops: Correct Solution

Part 1

Translate the following while loop into a for loop:

int tesm = 77;
while (tesm >= munso) {
    tesm += 2;
    strar(tesm);
    aemsa();
}

Solution

for (int tesm = 77; tesm >= munso; tesm += 2) {
    aemsa();
    strar(tesm);
}

Part 2

Translate the following loop into a for-each loop:

List<Mosce> poins;
...

for (int i = 0; i < poins.size(); i++) {
    poins.get(i).asseun();
    shede(4);
    vito(poins.get(i));
}

Solution

for (Mosce poin : poins) {
    vito(poin.get(i));
    shede(4);
    poin.get(i).asseun();
}

It is OK if you gave the variable for the individual collection element (poin) 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.
