This is from Khalid's
test.
Which method implementations will write the given
string to a file named "file", using UTF8 encoding?
IMPLEMENTATION A:
public void write(String msg) throws IOException {
FileWriter fw = new FileWriter(new File("file"));
fw.write(msg);
fw.close();
}
IMPLEMENTATION B:
public void write(String msg) throws IOException {
OutputStreamWriter osw =
new OutputStreamWriter(new FileOutputStream("file"), "UTF8");
osw.write(msg);
osw.close();
}
IMPLEMENTATION C:
public void write(String msg) throws IOException {
FileWriter fw = new FileWriter(new File("file"));
fw.setEncoding("UTF8");
fw.write(msg);
fw.close();
}
IMPLEMENTATION D:
public void write(String msg) throws IOException {
FilterWriter fw = FilterWriter(new FileWriter("file"), "UTF8");
fw.write(msg);
fw.close();
}
IMPLEMENTATION E:
public void write(String msg) throws IOException {
OutputStreamWriter osw = new OutputStreamWriter(
new OutputStream(new File("file")), "UTF8");
osw.write(msg);
osw.close();
}
I think the answer is B.
Thanks.
