- Write a class FileConverter with a constructor that accepts a String file name as its argument. It should store filename as its attribute (with a accessor getFilename(). The class should have the following methods: • createUpperCaseFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will convert all lines of the class attribute filename to upper case and write it to target file, line by line. • createRowCharCountFile(): Accepts a String parameter targetFilename. It will open up both the file specified in class attribute filename and the method parameter targetFilename. Then it will count the number of chars in each line of the class attribute filename and write it to target file line by line.
