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:
BiFunction<Integer, Double, Integer> val = (t1, t2) -> t1 + t2; //line n1 System.out.println(val.apply(10, 10.5));
What is the result?
Given:
Your design requires that:
fuelLevel of Engine must be greater than zero when the start()method is invoked.
The code must terminate if fuelLevelof Engineis less than or equal to zero.
Which code fragment should be added at line n1to express this invariant condition?
Given the content of /resourses/Message.properties:
welcome1="Good day!"
and given the code fragment:
Properties prop = new Properties ();
FileInputStream fis = new FileInputStream ("/resources/Message.properties"); prop.load(fis); System.out.println(prop.getProperty("welcome1")); System.out.println(prop.getProperty("welcome2", "Test"));//line n1 System.out.println(prop.getProperty("welcome3")); What is the result?
Given the code fragment:
Which code fragment prints red: blue: sma11: medium: ?
