Question
The number of bytes occupied by a character array of 10 elements.(a) 20 bytes(b) 60 bytes(c) 40 bytes(d) 120 bytes(vi) The method of Scanner class used to accept a double value is:(a) nextInt()(b) nextDouble()(c) next()(d) nextInteger()
Solution
-
The number of bytes occupied by a character array of 10 elements depends on the character encoding used. In most systems, a character is represented using 2 bytes (for UTF-16 encoding). Therefore, a character array of 10 elements would occupy 2*10 = 20 bytes. So, the answer is (a) 20 bytes.
-
The method of Scanner class used to accept a double value in Java is nextDouble(). So, the answer is (b) nextDouble().
