How to load reference a file as a File instance from the classpath

Question

I have a file that is in my classpath  e g  com path to file txt  I need to load or reference this file as a java io File object  The is because I need to access the file using java io RandomAccessFile  the file is large  and I need to seek to a certain byte offset   Is this possible  The constructors for RandomAccessFile require a File instance or String  path    If there s another solution to seek to a certain byte offset and read the line  I m open to that as well

Or use directly the InputStream of the resource using the absolute CLASSPATH path  starting with the   slash character      getClass   getResourceAsStream   com path to file txt       Or relative CLASSPATH path  when the class you are writing is in the same Java package as the resource file itself  i e  com path to      getClass   getResourceAsStream  file txt

This also works  and doesn t require a  path to file URI conversion   If the file is on the classpath  this will find it   File currFile   new File getClass   getClassLoader   getResource  the file txt   getFile
