Given:
final class Folder {//line n1
//line n2
public void open () {
System.out.print("Open");
}
}
public class Test {
public static void main (String [] args) throws Exception {
try (Folder f = new Folder()) {
f.open();
}
}
}
Which two modifications enable the code to print Open Close? (Choose two.)

Given the code fragment:

What is the result?
Word: why what when

Given the code fragment:

Assume that dbURL, userName, and password are valid.
Which code fragment can be inserted at line n1 to enable the code to print Connection Established?

Given the code fragment:
public class FileThread implements Runnable {
String fName;
public FileThread(String fName) { this.fName = fName; }
public void run () System.out.println(fName);}
public static void main (String[] args) throws IOException, InterruptedException { ExecutorService executor = Executors.newCachedThreadPool(); Stream<Path> listOfFiles = Files.walk(Paths.get("Java Projects")); listOfFiles.forEach(line -> { executor.execute(new FileThread(line.getFileName().toString())); // line n1
});
executor.shutdown();
executor.awaitTermination(5, TimeUnit.DAYS);//
line n2
}
}
The Java Projects directory exists and contains a list of files.
What is the result?

Given the code fragment:
public static void main (String[] args) throws IOException {
BufferedReader brCopy = null;
try (BufferedReader br = new BufferedReader (new FileReader("employee.txt")))
{ //
line n1
br.lines().forEach(c -> System.out.println(c));
brCopy = br; //line n2
}
brCopy.ready(); //line n3;
}
Assume that the ready method of the BufferedReader, when called on a closed BufferedReader, throws an exception, and employee.txt is accessible and contains valid text.
What is the result?
