"Observe that some combinations such as StandardOpenOption.CREATE, StandardOpenOption.READ do not make sense if put together and therefore an IllegalArgumentException will be thrown in such cases."
I think it might be that you can't specify READ for a Writer:

I think it might be that you can't specify READ for a Writer:
Code: Select all
import java.nio.charset.*;
import java.nio.file.*;
import java.io.*;
public class C15 {
public static void main (String...args){
try{
Path p = Paths.get("C:\\Users\\XXX\\Documents\\java\\certification\\1z0-804\\xxx\\abc.txt");
BufferedWriter bw = Files.newBufferedWriter(p
,Charset.forName("UTF-8")
,new OpenOption[]{StandardOpenOption.READ});
bw.write("abc");
bw.close();
}
catch(java.io.IOException e) {
e.printStackTrace();
}
}
}
Exception in thread "main" java.lang.IllegalArgumentException: READ not allowed
