Question

I can iterate in array using Pythons for loops as

arr = []
for e in arr:
    do smth. with each element

Does java has similar loop? If I will split the string in Java like this:

temp = str.split(delimiter);

Will I have array which can be looped with “for … in…” similar statement?

Answer 1

There is the foreach “statement”:

for (final E element: array) {
    // do whatever with element
}

It works with arrays and all kinds of Collections as well (Sets, Lists, Maps), and in general for any class X which implements Iterable<X>, ie, Iterable of itself (which means you can write a class to use in a foreach statement, which is nice).

So, you could write directly:

for (final String s: str.split(delimiter)) {
    // work with s
}

as .split() returns an array, which is directly useable with a foreach statement. That is, if you don’t need another variable to hold the array index for whatever reason.
