19.
}
20.
void area ( ) { System.out.println ("Rectangle"); }

}
Which two modifications enable the code to compile?
Given the code fragment:
List<String> listVal = Arrays.asList("Joe", "Paul", "Alice", "Tom");
System.out.println (
// line n1
);
Which code fragment, when inserted at line n1, enables the code to print the count of string elements whose length is greater than three?
Which two statements are true about localizing an application? (Choose two.)
