Use different Package to read file


I have a package name abc, where I have struct which is converting a text file into the numeric string so now I am trying to create the main package where I can open a file then I can run my package abc (inside the main package) to convert that data into the numeric and final step is to read that file line by line and print it out. Can you please help me with that?

Thank you,

Which item of the following list gives you hard time exactly?

  • create the main package
  • open a file
  • read file line by line
  • use your package to convert data
