asked on Problem with IO java class method, newOutputStream(CREATE), program won't compile
Hello Experts,
I am getting a compilation error with the program below. I don't understand why because the code is straight from the book. The problem according to Eclipse is the newOutStream() method which is supposed to come from the java.nio.file.StandardOpen

That worked great. I don,t understand why there is any problem with the code to begin with. It came straight out of the Joyce Farrell, Java Programming book. There is another similar problem program. The code is listed below. I tried to modify the statement similar to the way you presented the solution to the earlier problem, but it did not work. Eclipse is giving me an error message for the checkAccess(READ, EXECUTE) method. The error message is: "The method checkAccess(AccessMode, AccessMode) is undefined for the type Path". I am not sure if I should start another thread for this. I increased the points
package pathDemos;
import java.nio.file.*;
import static java.nio.file.AccessMode.*;
import java.io.IOException;
public class PathDemo3
{
public static void main(String[] args)
{
Path filePath = Paths.get("C:\\JavaPrograms\\Data.txt");
System.out.println("Path is " + filePath.toString());
try
{
filePath.checkAccess(READ, EXECUTE);
System.out.println("File can be read and executed");
}
catch(IOException e)
{
System.out.println("File cannot be used for this application");
}
}
}

I guess a lot of the API was changed in those 3+ years.
filePath.checkAccess(READ, EXECUTE);
filePath.getFileSystem().provider().checkAccess(filePath, READ, EXECUTE);

Yes, I was wandering about that.
Thanks. I will probably need more help with this chapter, but I'll start a new post.
