10,807 PointsExplaination of for statement
Hi,
I regularly see a statement of this sort: for (Treet treets : treet)
Could someone explain what this means? Thanks!

This is an example of an enhanced for-loop, or a for-each loop.
for (Treet treet : treets)
The first capitalized Treet is the data type of the treet that follows. The : can be read as "in", and is followed by the array that will be iterated over. It basically means for each treet of type Treet in the array called treets.
for (Treet treet : treets) {
System.out.println(treet);
}
For example, this piece of code will take each treet of type Treet in the array, treets, and print it.
Hope that helps. Here's a link to a bit more on enhanced for-loops.
