Iterator.hasNext() is one of the two main methods of the Iterator interface. It can be used on an Iterator to find out if there are any remaining objects to iterate over.
For example, it would be used like this:
Iterator iter = ...;
while (iter.hasNext()) {
// do something with iter.next()...
}

If method A calls method B and method B throws an exception, then method A must handle that exception. It does not have to throw the exception if it is in a try-catch block, but it must do something to deal with it.Note that this only applies to checked exceptions. If method B throws an unchecked exception, then A is allowed to ignore it.
How do you use the hasNext method in java but not have it block waiting for input?
hasNext() is a method of different classes in Java. If you mean java.util.Iterator.hasNext() or java.util.Scanner.hasNext(), it shouldn't block while waiting for input. That is part of the purpose of the hasNext() method - so that the caller can determine if there is more data without actually fetching the data.
