Traverse arraylist with iterator

When I wrote the note, I wanted to talk about it. What stringbuilder is not the stringbuffer in Java.
Looking at the traversal of the set, we can say that ienumerator is actually an iterator in Java, and it is dizzy. It also has a strange name to read!

Class Program
{
Static   Void Main ( String [] ARGs)
{
Arraylist arr1 =   New Arraylist ();

// Add element cyclically
For ( Int I =   0 ; I <   10 ; I ++ )
{
Arr1.add (I );
}

Ienumerator ENM = Arr1.getenumerator ();
While (ENM. movenext ()) {//When there is one, move to the next and return true;
Console. writeline (ENM. Current );//At the end of the record, stay in the last record, and return false
}
}
}
