Question:

Create a class(in JAVA) for FileHandling with following members

1. Final and Static field named as “bookPath”, which holds the address for the file, i.e; “Databook.txt”
2. Final and Static field named as “authorPath”, which holds the address for the file, i.e; “Dataauthor.txt”
3. Static method to write data in file. It takes two arguments: data and file path. Data is inserted at the end of the file while previous data remains. Data is single line to write in the file.
4. Static method to read data from file. It takes file path and returns whole file data.

Create Main class containing main method and show the working of FileHandling class without creating the object.

    }

  }

  public static void main(String[] args) {

    for (int i = 1; i <= 5; i++) {

      FileHandling.WriteFile(

        "Hello this is sample data #" + i + "n",

        "data.txt"

      );

    }

    System.out.println(

      "Reading Data From text file:n" + FileHandling.ReadFile("data.txt")

    );

  }

}

 

 

 

OUTPUT:
