Here is the code snippet.
read = new FileReader("trainfiles/"+filenames[i]);
br = new BufferedReader(read);
while((lines = br.readLine())!=null){
st = new StringTokenizer(lines);
while(st.hasMoreTokens()){
bw = new BufferedWriter(new FileWriter("files/file.txt"));
bw.write(st.nextToken());
bw.newLine();
}
}
Edit:
I am reading files from a directory. So, I need to open the reader in every loop. I have made some modification, but then also it is not writing to that file.
Here is the code:
for(i=0;i==0;i++){
if(filenames[i].matches(".*ham.*")){
System.out.println("ham:"+filenames[i]);
read = new FileReader("trainfiles/"+filenames[i]);
br = new BufferedReader(read);
while((lines = br.readLine())!=null){
st = new StringTokenizer(lines);
while(st.hasMoreTokens()){
System.out.println(st.nextToken());
bw.write(st.nextToken());
}
}
bw.close();
br.close();
}else{
System.out.println("spam:"+filenames[i]);
}
}
edit:
I modified the code, but no success,
while((lines = br.readLine())!=null){
st = new StringTokenizer(lines);
bw = new BufferedWriter(new FileWriter("files/file.txt"));
while(st.hasMoreTokens()){
System.out.println(st.nextToken());
bw.write(st.nextToken());
}
bw.close();
}
br.close();
And i am getting this error: Exception in thread "main" java.util.NoSuchElementException
at java.util.StringTokenizer.nextToken(StringTokenizer.java:332)
at Test.main(Test.java:30)
edit:
Thanks guys.. I figured it out. Actually I created an directory in eclipse and I did not refresh it to see the content. Its silly... anyways.thanks a lot
