I have tried two snippets of Java 1.7 code:
Snippet 1:
try {
BufferedReader in = new BufferedReader(
new InputStreamReader(myInputStream)); //from the Internet
String s;
out = new PrintWriter(new BufferedWriter(new FileWriter("file")));
while ((s = in.readLine()) != null){
out.write (s);
}
in.close();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Snippet 2:
try {
BufferedInputStream in = new BufferedInputStream(
myInputStream); //from the Internet
out = new BufferedOutputStream(new FileOutputStream("file"));
byte[] data = new byte[1024]; // 1 Kb randomly chosen as my buffer
int len=0;
while ((len=in.read(data)) != -1) {
out.write(data,0,len);
}
in.close();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Snippet 1 seems to perform approximately 2 to 6 times faster than snippet 2. However, I need to use Snippet 2 because I am reading a byte stream. Is there any way to improve the performance of snippet 2 so that it more closely matches snippet 1? Am I doing something wrong?
