Hi:
In my program, I need to write to many files very often when data is received. Presently, I have one method that writes data to files, where the file to be written to depends on the argument I pass it. Below is the simplified version:
void saveData(int whichFile, int data) {
try{
FileWriter outfile = new FileWriter(fileList[whichFile], true);
BufferedWriter out = new BufferedWriter(outfile);
out.write("" + data+"\n");
out.close();
} catch(IOException e) {
}
The problem is that because each file to be written to, calls saveData so often, there is major inefficiency in creating and closing the streams. I would like to keep the streams open for the duration of my class. However, when I put into the constructor of my class:
//declared outfile and out as members of the class
try{
outfile = new FileWriter(fileList[whichFile], true);
out = new BufferedWriter(outfile);
} catch(IOException e) {
}
out gets closed it seems when the constructor ends. So when saveData uses out.write("" + data + "\n"); I get an error.
Thanks. Your time and expertise is much appreciated.
