Once you get over the path problem you'll see that you can't execute a text file on windows, because text files are not executable programs. If you want to open the file rather than execute it use the Desktop class. See for example How to launch the default (native) application for a given file from Java?

File file = new File ("c:/documents and settings/Intel/whatever/file.txt");
Desktop.getDesktop().open(file);

Process p = Runtime.getRuntime().exec("cmd /c start notepad C:\\Documents and Settings\\INTEL\\My        Documents\\NetBeansProjects\\urldemo\\t1.txt");

//you can also provide other editor instead of notepad
