How to create a project from existing source in Eclipse and then find it

Question

I have created several  java files  All of them are located in one directory  I used a text editor to write these files  Now I want to switch to Eclipse  How can I do it  I have tried many ways  None of them works   ADDED   I think the common way is to have source in the eclipse folder called  workspace   So  how do I get my files in these directory  Should I use eclipse to create a new project from existing source and Eclipse will put all file to the workspace  Or I  should manually copy all my files to the workspace  Where should I put my class files than  Should I create a subdirectory  With which name   ADDED 2   When I try to create a project with name  game   the eclipse writes me that a project with such name already exist  But how can I open this project   ADDED 3   In my  workspace  I have created a subdirectory called  game   I copied all my  java file into this subdirectory  Then with Eclipse I created a new project with the name game  As a result  Eclipse created  classpath and  project files in the directory  game   It also created bin and src subdirectories  And now I think it is not the correct way to go  The source files are supposed to be in the  src  directory  Right  And at the moment all my  java files are in the  workspace game    ADDED 4   I did it other way around  With Eclipse I have created a new project with the name  game   As the result  Eclipse created a folder called  game  into folder  workspace   In  game  the folder I found  src  folder  I copied all my  java files into this folder  But now in the  Package Explorer  I cannot open  src  folder  So  how can I access my source files from Eclipse  Why Eclipse does not want to open the  src  folder

While creating a project from a full folder may or may not work within the workspace, there's a condition outside of the workspace that prevents starting a new project with a full folder.

This is relevant if you use numerous folder locations for sources, for example an htdocs or www folder for web projects, and a different location for desktop Java applications.

The condition mentioned occurs when Eclipse is told to create a new project, and given a full folder outside the workspace. Eclipse will say the folder isn't empty, and prevent creating a new project within the given folder. I haven't found a way around this, and any solution requires extra steps.

My favorite solution is as follows

Rename the full folder with an appended "Original" or "Backup.
Create the Eclipse project with the name of the full folder before the folder was renamed.
Copy all the relabeled full folders contents into the new project folder.

Eclipse should make a new project, and update that project with the new folder contents as it scans for changes. The existing sources are now part of the new project.

Although you had to perform three extra steps, you now have a backup with the original sources available, and are also able to use a copy of them in an existing project. If storage space is a concern, simply move/cut the source rather than fully copy the original folder contents.

Easiest Method    Put all source files into one directory named after your project  i e   ProjectName  You can keep this directory in your workspace or it can be somewhere else  Start a new project in eclipse and name it using that same project name  Uncheck the  use default location  box and find the directory where your project is unless your project is already in the workspace - then you must not uncheck the  use default location  box Click  next      Eclipse should be smart enough to figure out what s going on  After clicking next  it will show you all of the files it found in that directory  It will just automatically add those files to your project  Voil

There are several ways to add files to an existing Java project in Eclipse  So lets assume you have already created the Java project in Eclipse  e g  using File -  New -  Project    - and select Java project    To get Java files into the new project you can do any of the following  Note that there are other ways as well  The sequence is my preference    Drag the files into the Navigator view directly from the native file manager  You must create any needed Java packages first  This method is best for a few files in an existing Java package  Use File -  Import    - select File System  Here you can then select exactly which files to import into the new project and in which Java package to put them  This is extremely handy if you want to import many files or there are multiple Java packages  Copy the fires directly to the folder directory in the workspace and then use File -  Refresh to refresh the Eclipse view of the native system  Remember to select the new project before the refresh    The last one is what you did - minus the refresh
