How to make jar e-books with javax programming

Answer 1

Creating a jar e-book requires writing a java-based application and packaging the e-book file as a JAR file into the application.

The following was a simple step:

1 Create a new project using a java-based development tool (such as Eclipse or IntelJ Idia).

Create a new file in the project and name it "bookjava'.

3 Write the following code in bookjava.com:

```
import javaioFile;
import javaioIOException;

public class Book {
public static void main(String[] args) {
String filename = bookjava;
try {
File file = new File(filename);
Byte[] data = read the e-book (file);
write eBook (file data);
} catch (IOException e) {
eprintStackTrace();
}
}
}
```

4. Use the file manipulation API(such as fileinputream and fileoutputream) to create a new file and read the contents of the e-book.

```
import javaioFileInputStream;
import javaioFileOutputStream;

public class Read eBook {
public static Byte[] read e-book (String Filament) throws IOExceptional {
FileInputStream fis = new FileInputStream(filename);
FileOutputStream fos = new FileOutputStream(filename);
byte[] buffer = new byte[1024];
int len = 0;
while ((len = fisread(buffer)) != -1) {
foswrite(buffer 0 len);
}
fosclose();
fisclose();
return buffer;
}
}
```

5. Write the contents of the e-book into a new file using the file manipulation API of Java.

```
import javaioFileOutputStream;
import javaioIOException;

public class Write eBook {
public static void write e-book (String Filament Byte[] data) throws IOExceptional {
FileOutputStream fos = new FileOutputStream(filename);
foswrite(data);
fosclose();
}
}
```

6 Run a java-based application.

```
Book book = new Book();
bookmain();
```

The above are the general steps of making jar e-books that need to be implemented according to actual situations.
