Question

In Java, how do I get the index of the current element?

for (Element song: question){
    song.currentIndex();         //<<want the current index
}

In PHP, you could do this:

foreach ($arr as $index => $value) {
    echo "Key: $index; Value: $value";
}

Answer 1

You can’t, you either need to keep the index separately:

int index = 0;
for(Element song : question) {
    System.out.println("Current index is: " + (index++));
}

or use a normal for loop:

for(int i = 0; i < question.length; i++) {
    System.out.println("Current index is: " + i);
}

The reason is you can use the condensed for syntax to loop over any Iterable, and it’s not guaranteed that the values actually have an “index”
