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
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.
