and given the code fragment:

Which two code fragments, when inserted at line 1 independently, enable the code to print "Wie geht's?"

• A.currentlocale = new Locale();
  currentLocale.setLanguage ("de");
  currentLocale.setRegion ("DE");
• B.currentLocale = Locale.getInstance(Locale.GERMAN,Locale.GERMANY);
• C.currentLocale = new Locale ("de", "DE");
• D.currentLocale = new Locale.Builder ().setLanguage ("de").setRegion ("DE").build ();
• E.currentLocale = Locale.GERMAN;

Given:
IntStream stream = IntStream.of (1,2,3);
IntFunction<Integer> inFu= x -> y -> x*y;//line n1
IntStream newStream = stream.map(inFu.apply(10));//line n2
newStream.forEach(System.out::print);
Which modification enables the code fragment to compile?

• A.Replace line n1 with:IntFunction<UnaryOperator> inFu = x -> y -> x*y;
• B.Replace line n1 with:IntFunction<IntUnaryOperator> inFu = x -> y -> x*y;
• C.Replace line n2 with:IntStream newStream = stream.map(inFu.applyAsInt (10));
• D.Replace line n1 with:BiFunction<IntUnaryOperator> inFu = x -> y -> x*y;

Given the for loop construct:
for ( expr1 ; expr2 ; expr3 ) {
statement;
}
Which two statements are true?

• A.This is not the only valid for loop construct; there exits another form of for loop constructor.
• B.The expression expr1 is optional. it initializes the loop and is evaluated once, as the loop begin.
• C.When expr2 evaluates to false, the loop terminates. It is evaluated only after each iteration through the loop.
• D.The expression expr3 must be present. It is evaluated after each iteration through the loop.
