(i) int res = 'A'; What is the value of res? (ii) Name the package that contains wrapper classes.

(i) res = 65 (ii) java.lang

(i) Assigning a char to an int stores its Unicode value. 'A' is 65. Fix the anchors: 'A' = 65, 'a' = 97, '0' = 48 — almost every char question in this paper is answered from these three. (ii) All the wrapper classes — Integer, Character, Double, Boolean and the rest — belong to java.lang, along with String and Math. java.lang is imported automatically, which is why no import statement is ever needed for them. Careful: some published keys give java.util for this, which is wrong — java.util holds Scanner and the collection classes.
