What is the minimum SQL standard that a JDBC API implementation must support?

• A. SQL-2003
• B. SQL-92
• C. JDBC 4.0
• D. SQL 99

Which code fragments print 1?

• A. String arr [] = {"1", "2", "3"};
  List <? extends String > arrList = new LinkedList <> (Arrays.asList (arr));
  System.out.println (arrList.get (0));
• B. String arr [] = {"1", "2", "3"};
  List <Integer> extends String > arrList = new LinkedList <Integer> (Arrays.asList (arr));
  System.out.println (arrList.get (0));
• C. String arr [] = {"1", "2", "3"};
  List <?> arrList = new LinkedList <?> (Arrays.asList (arr));
  System.out.println (arrList.get (0));
• D. String arr [] = {"1", "2", "3"};
  List <?> arrList = new LinkedList <> (Arrays.asList (arr));
  System.out.println (arrList.get (0));
• E. String arr [] = {"1", "2", "3"};
  List <Integer> arrList = new LinkedList <> (Arrays.asList (arr));
  System.out.println (arrList.get (0));

Given the code fragment:
static void addContent () throws Exception {
Path path = Paths.get("D:\\company\\report.txt");
UserPrincipal owner = path.getFileSystem().getUserPrincipalLookupService().lookupPrincipalByName("Bob");
Files.setOwner(path, owner);
// insert code here - Line **
br.write("this is a text message ");
}
System.out.println("success");
}
Assume that the report.txt file exists.
Which try statement, when inserted at line **, enables appending the file content without writing the metadata to the underlying disk?

• A. try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption [] {StandardOpenOption.APPEND, StandardOpenOption.SYNC));){
• B. try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption []
  {StandardOpenOption.CREATENEW, StandardOpenOption.APPEND,
  StandardOpenOption.SYNC}}
  }
• C. try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption [] {StandardOpenOption.APPEND, StandardOpenOption.DSYNC}
• D. try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption [] {StandardOpenOption.APPEND, StandardOpenOption.ASYNC});) {
• E. try (BufferWriter br = Files.newBufferedWriter (path, Charset.forName ("UTF - 8"), new
  openOption []
  {StandardOpenOption.CREATE, StandardOpenOption.Append, StandardOpenOption.DSYNC}};}
  {

Which two statements are true about RowSet subinterfaces?

• A. A FilteredRowSet object filter can be modified at any time.
• B. A cachedRowSet provides a connected view of the database.
• C. A webRowSet returns JSON-formatted data.
• D. A jdbcRowSet object provides a JavaBean view of a result set.
