I have been watching some LinkedList videos to try and understand what it is. But I see a lot of people having code like
for(String x : model)
Can anyone help me understand what ":" does in this code besides attaching x to "model" or is that all it does?
It means the loop will iterate through each object of the list
String x declares a String named x
model is the list of String you want to iterate through
: is the operator making the compiler doing this operation.
You can read the for like this : For each String in model, use x as variable and do the following operations.
you can then use x to do the operations you want on each elements of the list
This is the syntax of the enhanced for loop. It marely means that you're iterating over all the elements in model, where in each iteration the String x is assigned with the current element so you can use in the loop's body.
Similar to mathematical notation that represents elements in a set.
Read left to right; For all string's x that are elements in model, do .
