title: Importing .java files on to a Java Project in eclipse
body: <p>I'm working on a Java project in Eclipse that outputs a bunch of text/numbers on to an excel file. I am using a bunch of quickTapSurvey .java files for the project. QuickTapSurvey is just a survey app where users can add/modify the questions according to their needs. I imported the .java files by right clicking on the "default package" and then clicking on the "File system" category. Now that I have all the .java files in my project, they have red "X" marks next to their names, which I am assuming denotes an error (look at the attached snapshots). The code itself has red underlines everywhere. Can someone please tell me what I am doing wrong.</p>
