Read txt and maintain the same formatting in JAVA

[Pratyush]

Hello, I don't understand how can I keep the same format a. Txt

Virtually the read, I put in a string and then put it here:

JTextArea textarea = new JTextArea (string);

I read the file with this code:

While (filebuffer1.ready ()) (
lic + = (filebuffer1.readLine ());
)

them is very likely that mistake.

There are other components, or methods of reading, which retain the same formatting of source files?

Assuming that "filebuffer1" is a BufferedReader, why not get what they want is the way in which the method. ReadLine ()

public String ReadLine ()
throws IOException

Reads a line of text. A line is considered to be terminated by any one of a line feed ( '\ n'), a carriage return ( '\ r'), or a carriage return followed immediately by a linefeed.

Returns:
A String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached
Throws:
IOException - If an I / O error occurs

Law and a "single line" and you will return without the carriage return characters from a String object.
You must enter you the terminator line ending at the bottom of the String received.

To avoid mile-milla String (the + operator applied to two creates a third String String that is the result of the first two concatenated in Java String objects are immutable) in your cycle you can declare object "lic" as a StringBuilder and use his method. append () to concatenate the String returned by the BufferedReader, for example:

 Lic StringBuilder = new StringBuilder; 

  while (filebuffer1.ready ()) ( 
             String line = filebuffer1.readLine ();  
    	      lic.append (line) / / concatenate the string read from the buffer 
             lic.append ( "\ n"); / / concatenate the character to end of line 
           )

Read the text file all at once.

 Scanner in = new Scanner (txt file). UseDelimiter ( "\ \ Z"); 
  try ( 
      String fulltext = in.next (); 
  ) Finally ( 
      in.close (); 
  )

  try ( 
      String fulltext = in.next (); 
  ) Finally ( 
      in.close (); 
  )

Good to know ...
What is the string passed as a parameter to the method useDelimiter ()? A regular expression?

[Ackley]

Yes, it is a regular expression which belongs to the species (rare) of regular expressions that you understand ".

\ Z means "until the end of the input, except the character that signals the end of the input, if any."

Becomes "\ \ Z" because \ is a special character in Java strings and can type in a string "must use the escape '\'.
