java foreach skip first iteration

Question

Is there an elegant way to skip the first iteration in a Java5 foreach loop ?

Example pseudo-code:

for ( Car car : cars ) {     
   //skip if first, do work for rest
   .
   .
}

Answer 1

Elegant? Not really. You'd need to check/set a boolean.

The for-each loop is for all practical purposes fancy syntax for using an iterator. You're better off just using an iterator and advancing before you start your loop.

Answer 2

You can use a counter. Though not so mature coding, still I find it the easiest way to skip the first element from a list.

    int ctr=0;
    for(Resource child:children) {
    if(ctr>0) { //this will skip the first element, i.e. when ctr=0
    //do your thing from the 2nd element onwards
    }
    ctr++;
    }

Answer 3

With new Java 8 Stream API it actually becomes very elegant. Just use skip() method:

cars.stream().skip(1) // and then operations on remaining cars

Answer 4

I wouldn't call it elegant, but perhaps better than using a "first" boolean:

for ( Car car : cars.subList( 1, cars.size() ) )
{
   .
   .
}

Other than that, probably no elegant method.  

Answer 5

SeanA's code has a tiny error: the second argument to sublist is treated as an exclusive index, so we can just write

for (Car car : cars.subList(1, cars.size()) {
   ...
}

(I don't seem to be able to comment on answers, hence the new answer. Do I need a certain reputation to do that?)  

Answer 6

Not so elegant but work with iterators

Iterator<XXXXX> rows = array.iterator();
if (rows.hasNext()){
    rows.next();
}
for (; rows.hasNext();) {
    XXXXX row = (XXXXX) rows.next();
}
