问题 Excuse me if this has been asked before. My search did not bring up any other similar question. This is something that surprised me in Java. Apparently, the enhanced for-loop only accepts an array or an instance of java.lang.Iterable . It does not accept a java.util.Iterator as a valid obj reference to iterate over. For example, Eclipse shows an error message for the following code. It says: " Can only iterate over an array or an instance of java.lang.Iterable " Set<String> mySet = new

问题 I'm pretty sure this has worked before in some code I have written, not sure what I am missing here. The following code does not change the string values in my list.

"move " + item : "move -check " + item); EDIT : Just to clarify, the list remains the same as when it was created. EDIT : Apologies, the items list (listBox1.Items) contains alphanumeric strings as follows. J00123456
