String x[] = {"SAMSUNG", "NOKIA", "SONY", "MICROMAX", "BLACKBERRY"}; Give the output of the following statements: (i) System.out.println(x[1]); (ii) System.out.println(x[3].length());
Topic: Array of Strings

Answer
Exam answer
(i) NOKIA (ii) 8
Explanation
(i) Counting from 0: x[0] is SAMSUNG, x[1] is NOKIA. The off-by-one error — answering SAMSUNG — is what the question is testing. (ii) x[3] is MICROMAX, and length() counts its characters: M-I-C-R-O-M-A-X = 8. Note the two different meanings of length here: x.length would be 5, the number of words in the array, while x[3].length() is 8, the number of characters in one word. Array length has no brackets; String length() has them.
