You don't have to explain yourself. I was just curious as to why you said it.

I just find it strange when you help someone out, you thank that person for letting him/her be helped.

Thanks.

Hi all

private static void readFile(String fileName) {

try {

Scanner scanner = new Scanner(new File(fileName));

scanner.useDelimiter

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

while (scanner.hasNext()) {

System.out.println(scanner.next());

Thanks

If it's lines you're interested in, then you can use the hasNextLine() and nextLine() methods:

private static void readFile(String fileName) {

try {

Scanner scanner = new Scanner(new File(fileName));

while (scanner.hasNextLine()) {

System.out.println(scanner.nextLine());

}

scanner.close();

} catch (FileNotFoundException e) {

e.printStackTrace();

}

}

Hi all

guess what\\when i try the method that i found

sc.useDelimiter

(System.getProperty("line.separator"))

it doesnot show the lines

when i use the while (sc.hasNextLine())

it write null in the file

and when i tried while (sc.nextLine() )

it gaves me incomptatible error

here the code

Scanner sc = null;

try {

sc = new Scanner(new BufferedReader(new FileReader("xanadu.txt")));

int number=0 ;

String str ="";

sc.useDelimiter

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

while (sc.hasNext() )

//while (sc.hasNextLine())

//while (sc.nextLine() )

{

if (sc.hasNextInt())

{

number = sc.nextInt();

target+=number+"";

}

// .... and so............

else

{

str = sc.next();

target += convert(str) +" ";

}

}

}finally {

if (sc != null) {

sc.close();

}

You're using one Scanner for two different purposes: reading lines, and reading tokens within each line. Try using two Scanners instead: Scanner sc0 = new Scanner(new File("xanadu.txt"));

while (sc0.hasNextLine())

{

String line = sc0.nextLine();

Scanner sc1 = new Scanner(line);

while (sc1.hasNext())

{

// read and process the token

}

}
