i have this code, and i would like to know what the “:” mean in the function
Element[][] grid = readFile();
for (Element[] ea : grid) {
for (Element e : ea)
System.out.print(e.getChar());
System.out.println();
In terms of a language equivalent, you can think of it as the word “in”. You can read it as “for each Element ‘e’ in ‘ea'”.
Here’s the documentation on that type of loop: http://docs.oracle.com/javase/1.5.0/docs/guide/language/foreach.html
