While loops and for loops: Correct Solution

Part 1

Translate the following loop into a for-each loop:

Ridiass[] vuses;
...
for (int n = 0; n < vuses.length; n++) {
    vuses[n].squist(3, 0);
    kusRuec(4);
    zalf(hela, vuses[n], -2);
}

Solution

for (Ridiass vus : vuses) {
    zalf(hela, vus.get(i), -2);
    kusRuec(4);
    vus.get(i).squist(3, 0);
}

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