Java ,For loop command

Question

What is the meaning of this?

for(Ship s: p.ships)

Ship is the class, s is the object of the class Ship, and p is the player.

These are commands from the game Battleship.

`for(int i = 0; i < p.ships.size(); i++){ Ship s = p.ships.get(0); }` — Youcef LAIDANI, Jun 04 '18 at 17:19

It iterates through all Ships contained in p, See: https://stackoverflow.com/questions/85190/how-does-the-java-for-each-loop-work — JoschJava, Jun 04 '18 at 17:20
Basically the system is traversing the list of all the ships of a player. — ℛɑƒæĿᴿᴹᴿ, Jun 04 '18 at 17:44

This code means that p.ships is a some of collection implements inteface Iterable.

for(Ship s: p.ships)

It is a foreach loop. Syntax sugar which was introduced in java 5.

This is equivalent of this statement above:

for (Iterator<Ship > i = p.ships.iterator(); i.hasNext();) {
    Ship s= i.next();
}
