I have created a pkg for my regular simple commands. They are non-static, to be more extensible, but somewhat more time-consuming to use because of creating object to use one. My other classes use them.

$ ls  *.java
CpF.java      IsBinary.java      RmLn.java        Tools.java
F2S.java      IsRoot.java        SaveToDisk.java  WordCount.java
Filters.java  ModRelativePaths.java  SetWord.java     WordNumber.java
Find.java     powerTools.java        Sort.java

Which option would you choose to use them easier?

1. to develop a small interface like 'powerTools.java' for the pkg.
2. to create a class with static methods for them.
3. to add a static method to each class
4. to stop overusing 'creating too many files' and centralising some?
5. sthing else?
