Remove package statement Program plan: Import the required packages into the program. Declare the required variables. Get the file input path from the user as the command line arguments. Check the input argument value is valid one or not. Check the input argument path exists or not. Check the input path is a directory or not. If it is not a directory, then display the error message. If it is a directory, then list the file content of the directory. If the file contents are directory, then get the directory name starting with “chapter” and prepare to remove the package statement. Call the “removePackageStatementFromFilesInDirectory()” method to remove the package statement. The “removePackageStatementFromFilesInDirectory()” method lists the files available in each directory. This method gets the files name that end with “.java”. This method calls the “removePackageStatment()” method to remove the package name in each file that end with the name “.java”. The “removePackageStatment()” method reads each file that ends with the name “.java” and removes the package name “package chapteri;”at the beginning of each file.
