simple loop syntax( ; ;), ( something : somthing)

[xcallmejudasx]

I'm curious as to all the different ways to write a for loop? I know how the standard

for(starting value; value to reach; increment value){
}

works. Could someone explain

for(something1 : something2){
}

I'm assuming it automatically starts at 0, something1 is the value to reach, and something2 is the increment value? Or maybe it increments++ start at something1 until it reaches something2?

If there are any other styles of writing a for loop(also that :? thing in if statements is confusing) feel free to toss them in here with a little explanation also.

Look here:
The for Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

That gives a basic rundown of the two types.

for(item : array) is used to iterate through an array or collection.

In most of the time I found that lots of well experienced Java programmers use this way. They say that, iteration on an array gives more performance in execution within short period of time in VM.

But the case is, use default iteration increment all the time, 1
