Problem in reading file in java

[TechGate]

Hello,
I work on a code that reads a csv file (and performs calculations based on information) I tested the program on a file "test", and it works. The problem is that the file "prod" is not read.

Exception occurred during event dispatching:
java.lang.OutOfMemoryError
<<no stack trace Available>>

Note that the file "test" contain 15 fields, while the file "prod" contains 600. It is more than 15MB. Nothing happens in the panel config:-Xmx300M Java. Basically I have a problem in reading a file. I have tried all my possibilities but, none worked for me.

Hello,
Even I have a similar kind of a problem with my code. I think it's a character story line end, because my function that retrieves the line to bring in an element vector stops on a newline or `\ n '. But when I copy 1 single line (wordpad) File "test" and that I test program. With a software that shows all the characters I see nothing.

Hello,
This is my code, please check it and if there are any mistakes then please do guide me.

Public Vector fgets(String file){
        
        String rtch = "\ n";
        Vector v = new Vector();
        String str = stringReadFromFile(file);
        StringTokenizer line = new StringTokenizer(str, rtch);
        while (line.hasMoreTokens())
	    v.addElement(line.nextToken());
        return v;
        }
    }

Hey guys
This is my part of code, just have a look at it.

Public String stringReadFromFile(String r_file){
        File f;
FileReader in = null;
String bk = "";
	try{
	    f = new File(r_file);
in = new FileReader(f);
	    int sz = (int) f.length();
	    char[] dt = new char[sz];
	    int chrd = 0;
	    while(chrd <sz)
	        chrd + = in.read(dt, chrd, sz - chrd);
return = new String(dt);
            in.close();
            return bk.substring(0, return.length());
	    }
	catch(Exception e){
	    return "2";
	    }
	}

Hello,
If it is to read line by line, both directly use a BufferedReader. In passing it must close the file in a finallyAnd prefer ArrayList to Vector in a single-threaded. Just see the code below

Public List fgets <String>(String file) throws IOException{
        ArrayList lt = <String> new ArrayList <String>();
        BufferedReader br = new BufferedReader(new FileReader(file));
        try {
        	String ln;
        	while ( (ln = br.readLine()) != null) {
        		lt.add(ln);
        	}
        } finally {
        	br.close();
        }
        lt.TrimToSize();
        return lt;
    }

Hello,
Error IOExpection , I recovered on another class upstream. I copied your function but it leaves me an error that I can not understand.

"WriteReadFile.java": <identifier> waited in line 151, column 17

What does this means. Do you have any idea about it. Thank you in advance.
