Java – Which software to use for continuous integration of a Java web project

for (Iterator<String> i = someIterable.iterator(); i.hasNext();) {
    String item = i.next();
    System.out.println(item);
}

Note that if you need to use i.remove(); in your loop, or access the actual iterator in some way, you cannot use the for ( : ) idiom, since the actual iterator is merely inferred.

As was noted by Denis Bueno, this code works for any object that implements the Iterable interface.

Also, if the right-hand side of the for (:) idiom is an array rather than an Iterable object, the internal code uses an int index counter and checks against array.length instead. See the Java Language Specification.

You might want to check out Nose and the Xunit output plugin. You can have it run your unit tests, and coverage checks with this command:

nosetests --with-xunit --enable-cover

That'll be helpful if you want to go the Jenkins route, or if you want to use another CI server that has support for JUnit test reporting.

Similarly you can capture the output of pylint using the violations plugin for Jenkins
