" import javaexcer.* "
In the left panel, I don't know what to do?
I will appreciate any helpfull information.

Answer 1

The solution would depend on how the classes for javaexcer library should be made available to a given project.
1. If you have a folder javaexcer with some classes in it and you would like to make it available to a jse8 project:
Right-click on the project in the explorer, select 'Properties' to bring up the Project Properties window.
Click on Libraries categories on the left panel.
Select 'Add Jar/Folder' to add the library directory. (Pl. remember to select the parent directory of javaexcer folder, because javaexcer should itself be available as a package on the classpath).
If your library is a jar file instead of a directory (that is if you have some jar file like javaexcer.jar which has the class files), perform the same step as above but select the jar file to add in 'add jar/folder' dialog.
2. If the library is used by many projects, then choose 'Tools | Library Manager' dialog and click 'Add Library' button to add a new custom library. Then select the newly created library and select 'Add Jar/folder' to add classes/jars to this custom library. Once you have set the custom library,. for any given project , perform the same steps as '1' but choose 'Add Library' instead of 'Add Jar/Folder'.
3. If you have the sources for jacaexcer and would like the sources to be complied along with the main project:
Right-click on the project in the explorer, select 'Properties' to bring up the Project Properties window.
Select 'Sources' category.
Select 'Add Jar/Folder' next to 'Source Package Folders' and add the source directory for javaexcer.
