Hi I have downloaded the JavaRanchCommon.zip file and saved this to I:\Java directory on the Unix machine where I am doing the assignments. Do I have to unzip this file? What is the jar file, is this the same as the zip file? Do I add I:\Java; I:\Java\JavaRanchCommon.zip to my classpath and place "import com.javaranch.common" at the top of my DaysOld.java file? What does the path "com..." mean? Thanks for your help Yen

No you dont have to unzip the file
JAR is Sun's name for a .zip file. As far as I know they are identical
Yes you add add I:\Java\JavaRanchCommon.zip to you classpath
You add import com.javaranch.common.* ; at the top of your DaysOld.java file
Com is the root Directory of the "package" in the JavaRanchCommon.zip
Good luck [This message has been edited by Johannes de Jong (edited August 20, 2001).]

Johannes is right. Depending on the properties of your 'unzip'program (I mean if your zip program allows to view the content of a zip-file unzipping is not needed) you can nevertheless unzip the files to look at the source code of the classes inside and/or add changes etc.
