Create a Object[][] data which can read text file.Then do that. Create the 2D array and store the data in it.
Also when posting code use code tags. Paste code, highlight it and click CODE button.

How to read text file line by line...?
how to read text file line by line, but the linefeed is defined by user, return list of string, each line of file is a item of list?
please help me.
Thanks very muchBrynjar wrote:
In Groovy, you would do something like:
linefeed = "\n" //or "\r\n" if the user chose so
lines = new File('pathtofile').text.split("${linefeed}")This is one of the things that has always annoyed me about Sun's sdk, i.e. the lack of easy ways to do things like that. You always end up making your own utilities or use something like Apache's commons.io. Same goes for jdbc and xml - I'll wait for appropriate topics to show how easy that is in Groovy :)I generally agree, but what I really don't like about the Groovy text-file handling niceties: They don't care about encoding/always use the default encoding. And as soon as you want to specify the encoding, it gets a lot more complex (granted, it's still easier than in Java). -

How to read text file efficiently?
I use CharBuffer to read text file:
private List<String> load() throws IOException {
final String B = "<BODY>";
final String E = "</BODY>";
List<String> docs = new ArrayList<String>();
for (File file : files) {
FileReader reader = new FileReader(file);
CharBuffer buffer = CharBuffer.allocate(BSIZE);
StringBuilder sb = new StringBuilder();
while (reader.read(buffer) != -1) {
char[] dst = new char[buffer.length()];
buffer.get(dst);
sb.append(dst);
buffer.clear();
String s = sb.toString();
System.out.println(file + ": " + s.length());
int start = 0;
int i, j;
while ((i = s.indexOf(B, start)) != -1) {
j = s.indexOf(E, i + B.length());
docs.add(s.substring(i + B.length(), j));
start = j + E.length();
//System.out.printf("%d %d %d%n", i, j, start);
return docs;
}The file size is 1324350, but the code say it is 772802.
What's wrong with this code?
I want to read text file as quickly as possible.
Is this code the right way to read file?
Should I use FileReader or nio Channel and ByteBuffer?
Any suggestions are welcome!You are reading the file as if it were encoded in UTF-16. Each character uses two bytes so you have half the number of characters as you had bytes.
The following code reads an entire file in one hit.
public static String readText(File file) throws IOException {
byte[] bytes = new byte[(int) file.length()];
DataInputStream dis = new DataInputStream(new FileInputStream(file));
try {
dis.readFully(bytes);
} finally {
dis.close();
return new String(bytes, "UTF-8"); // or whatever your file encoding is.
}But you can still have less characters than bytes if there are any non ASCII-7 characters. -

How to read text file by clicking on text file ?
Hello.. friends
I have made a java editor. I want to pass file name to a function in application by clicking on particular text file.
I assoiciated *.text file type with my application. when I click on text file application is run but I file is not read by my java application.
For example : in windows System all text are oppened in notepad when we click on any text file.
How to do this thing. please suggest me and if possible show me a sample code.
ThanksIf you are doing this in a web application you can set the content type appropriately and the file will open.
If you are doing this standalone you can use the Java RunTime class and execute something like this as the command "notepad.exe c:\\myfile.txt" which should open it up on a Windows operating system. -

fifa1509Does it compile? Does it do what you want when you run it?
If you have a problem, say what that problem is (cut and paste any
compiler error message).
One small point is that you could actually print the stack trace as this
will be much more informative if you have a problem.catch (IOException exception)
exception.printStackTrace();

How can I read text files from LAN if I only know the hostname?
I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
<p>1. How can I read text files from LAN if I only know the hostname, or IP address?
<p>2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.
(ex. how can I read the 120th line?)
<p>Please help!
<p>sorry for the bad englishI'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
1. How can I read text files from LAN if I only know the hostname, or IP address?You need to know the URL of the file. You need to know the hostname, port, protocl and relative path.
The hostname is server, not file.
2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.Use the seek() to get to a random byte.
(ex. how can I read the 120th line?)The only way to find the 120th line is to read the first 120 lines. You can use other file formats to find the 120th line without reading the whole file but to need to be able to detremine where the 120th line is
