While loops and for loops: Correct Solution

Part 1

Translate the following loop into a for-each loop:

Shenpog[] dreis;
...

for (int n = 0; n < dreis.length; n++) {
    dreis[n].ricde();
    ollpuk();
    pidNoison(dreis[n]);
}

Solution

for (Shenpog drei : dreis) {
    pidNoison(drei.get(i));
    ollpuk();
    drei.get(i).ricde();
}

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