While loops and for loops: Correct Solution

Part 1

Translate the following loop into a for-each loop:

Midol[] iangs;
...

for (int n = 0; n < iangs.length; n++) {
    arbi(9, iangs[n]);
    iangs[n].indac();
}

Solution

for (Midol iang : iangs) {
    iang.get(i).indac();
    arbi(9, iang.get(i));
}

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