Hi everyone!

I'm new to Java and I was wondering if anyone could help me with a program I'm working on. I have to read in a text file (I know how to do that part) and count the number of sentences in it, then save all the sentences to an array so I can pull out, say, sentence 70 on demand.

Any help will be greatly appreciated, thanks!

import java.io.*;
public class FiletoArray {
public static void main(String args[])
{
try
{
FileInputStream f=new FileInputStream("C:/Users/user/Desktop/aa.txt");
String s[]=new String[500]; //To store data from file
String temp; //Used to retrive current line data
int i=0;
System.out.println("ENTER DATA");
DataInputStream di=new DataInputStream(f); //Used to retrive any types of data
BufferedReader br=new BufferedReader(new InputStreamReader(di));

System.out.println(br.readLine());
while((temp=br.readLine())!=null)
{

s[i]=temp;
System.out.println(s[i]);
i++;
}
di.close();
System.out.println("NUMBER OF LINES IN THE FILE: "+(i+1));

}
catch(Exception e)
{
System.out.println(e);
}
}
}

import java.io.*;
public class FiletoArray {
public static void main(String args[])
{
try
{
FileInputStream f=new FileInputStream("C:/Users/user/Desktop/aa.txt");
String s[]=new String[500]; //To store data from file
String temp; //Used to retrive current line data
int i=0;
System.out.println("ENTER DATA");
DataInputStream di=new DataInputStream(f); //Used to retrive any types of data
BufferedReader br=new BufferedReader(new InputStreamReader(di));

System.out.println(br.readLine());
while((temp=br.readLine())!=null)
{

s[i]=temp;
System.out.println(s[i]);
i++;
}
di.close();
System.out.println("NUMBER OF LINES IN THE FILE: "+(i+1));

}
catch(Exception e)
{
System.out.println(e);
}
}
}

import java.io.*;
public class FiletoArray {
public static void main(String args[])
{
try
{
FileInputStream f=new FileInputStream("C:/Users/user/Desktop/aa.txt");
String s[]=new String[500]; //To store data from file
String temp; //Used to retrive current line data
int i=0;
System.out.println("ENTER DATA");
DataInputStream di=new DataInputStream(f); //Used to retrive any types of data
BufferedReader br=new BufferedReader(new InputStreamReader(di));

System.out.println(br.readLine());
while((temp=br.readLine())!=null)
{

s[i]=temp;
System.out.println(s[i]);
i++;
}
di.close();
System.out.println("NUMBER OF LINES IN THE FILE: "+(i+1));

}
catch(Exception e)
{
System.out.println(e);
}
}
}

Thanks for that, but it seemed to just print the text file to the screen.

Here you are.

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
import java.util.regex.Pattern;


public class SentenceCounter {
	private static final Pattern pattern = Pattern.compile( "\\." );

	public static void main(String[] args) throws FileNotFoundException {
		Scanner scanner = new Scanner( new File( "E:\\file.txt") ).useDelimiter( pattern );
		List<String> sentences = new ArrayList<String>();

		while( scanner.hasNext() ){
			String sentence = scanner.next().trim().replaceAll("[\r\n]+", " ") + ".";
			sentences.add( sentence );
//			System.out.println( sentence );
		}
	}
