Hi NLSurfMan,
I ceate a coding below , it always give me error:
java.io.FileNotFoundException: c:\abc\file.rtf (The process cannot access the file because it is being used by another process)
I have closed the FileReader and BufferedReader. I still have this problem. Why. Thanks. Gary
int c;
String text="";
File filename=new File("c:/abc/file.rtf");
FileReader fileReader =new FileReader(filename);
BufferedReader bReader=new BufferedReader(fileReader);
while ( (c=bReader.read())!=-1 ) {
text=text+(char)c;
bReader.close();
fileReader.close();
System.out.println("text="+text);
text=text+" I want to make some change here";
File filename1=new File("c:/abc/file.rtf");
BufferedWriter bWriter =new BufferedWriter(new FileWriter(filename1));
bWriter.write(text,0,text.length());
bWriter.close();
