Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Yes - if you have a Standard or Advanced level license of ArcGIS 10.1 for Desktop then you can use the Extend Line (Editing) tool to extend them (with a large value for the length parameter) until they meet another line. You may have to "encircle" your existing data to ensure that a line is always reached.
However, I am not at all sure that this is what you really want to do, so if not, some more details in your Question about your precise requirements and constraints would be worthwhile.
