Hi there
I came across this snippet and taught if you can give me some details for the below "for" loop:

for(Object name : v){
System.out.println(name);
}
say v is a vector. This type is used mainly in fileI/o Streams.
how exactly the loop is executed.

Thanks in advance

The "enhanced for" loop is new with Java 5.0. Basically, for(Object name : v) means for each Object in v (where "name" is a variable referencing the object of that iteration).

This saves you the trouble of writing index code, like for(int x = 0; x < v.size(); x++), and then pulling out the element with something like v.get(x).
