Thanks everybody for the help. What I need to do is the following:
**Open a file for reading**
**Read the first token [String] in the file**
**Report the next Read_Cursor_Position**
**Return the token**
**Close the file**
**Reopen the file**
**Read the *second* token from the file**
and so on and so forth until all the necessary data has been read. I am new to Java, but in C++ tellg or tellp is used to extract the cursor position and getline for reading just the one token from a file. I hope this explanation better explain my question.
After writing a method that outputs data with a delimiter to a UTF file, I am now trying to extract the data from the UTF file. The way the data has to be extracted is one token at the time, the tokens, as I said before, have a delimiter and all Java has to do is read the file's token until the delimiter is found. Here is the code for the writer method:
public void writeData(String data) throws IOException {
try {
dout.writeUTF(data);
dout.writeBytes("^");
} catch(IOException e) {
throw e;
}
}
and here is the reader:
public void readData() throws IllegalStateException {
try {
apstr = new StringBuilder();
while(scan.hasNext()) {
apstr.delete(0,apstr.length());
apstr.append(scan.next());
System.out.println("The token is: " + apstr);
}
} catch(IllegalStateException e) {
scan.close();
throw e;
}
scan.close();
}
The file contains the following data: Java^C++^PHP^ and the output is: Java^C++^PHP^ but all I want to read is the word Java
How can I make Java do the same thing?
by the way, how do I go about posting a new question? There is no button on this web page that says "Post a new question". Thanks in advance.
