	}

	

    return 0;

}

the data file is alphabet.dat and its just the alphabet in all caps.

There are a couple of ways you could probably do this. Here are two that aren't very different:

import java.io.*;


public class Main {


	public static void main(String[] args) {

		char[] array = new char[30];

		int cnt;

		

		try {

			FileReader ifp = new FileReader("alphabet.dat");

			

			if(ifp != null) {

				for(cnt = 0; cnt < 26; cnt +=1) {

					array[cnt] = (char)ifp.read();

					System.out.format("%c", array[cnt]);

				}

				

				System.out.print(System.getProperty("line.separator"));

				

				for(cnt = 0; cnt < 10; cnt +=1) {

					System.out.format("%c", array[cnt]);

				}

				

				System.out.print(System.getProperty("line.separator"));

				

				for(cnt = 20; cnt < 26; cnt += 1) {

					System.out.format("%c", array[cnt]);

				}

				

				System.out.print(System.getProperty("line.separator"));

								

				System.out.format("%c%s", array[10], System.getProperty("line.separator"));

				

				for(cnt = 26; cnt > -1; cnt -= 1) {

					System.out.format("%c", array[cnt]);

				}

				

				System.out.print(System.getProperty("line.separator"));

			}

		} catch (FileNotFoundException e) {

			e.printStackTrace();

		} catch (IOException e) {

			e.printStackTrace();

		}

	}


}

Here is the second one; just slightly different:

import java.io.*;


public class Main {


	public static void main(String[] args) {

		char[] array = new char[30];

		int cnt;

		

		try {

			FileReader ifp = new FileReader("alphabet.dat");

			

			if(ifp != null) {

				if(ifp.read(array, 0, 26) > 0) {

					for(cnt = 0; cnt < 26; cnt +=1) {

						System.out.format("%c", array[cnt]);

					}

					

					System.out.print(System.getProperty("line.separator"));

					

					for(cnt = 0; cnt < 10; cnt +=1) {

						System.out.format("%c", array[cnt]);

					}

					

					System.out.print(System.getProperty("line.separator"));

					

					for(cnt = 20; cnt < 26; cnt += 1) {

						System.out.format("%c", array[cnt]);

					}

					

					System.out.print(System.getProperty("line.separator"));

									

					System.out.format("%c%s", array[10], System.getProperty("line.separator"));

					

					for(cnt = 26; cnt > -1; cnt -= 1) {

						System.out.format("%c", array[cnt]);

					}

					

					System.out.print(System.getProperty("line.separator"));

				}

			}

		} catch (FileNotFoundException e) {

			e.printStackTrace();

		} catch (IOException e) {

			e.printStackTrace();

		}

	}


}

They both output:

abcdefghijklmnopqrstuvwxyz

abcdefghij

uvwxyz

k

 zyxwvutsrqponmlkjihgfedcba

when alphabet.dat is in the same directory as the class file.
