Which of the following characters does not need to have an associated “closing” character in a Java program?
a) {b) (
c) [
d) <
e) all of these require closing characters
Answer: d.
Explanation: { is used to open a block, and so } is needed to close the block. ( is used to open an expression and so ) is needed to close an expression. [ is used to start an array index so ] is needed to close the array index. < is “less than” and > is “greater than” and these are not needed together, so < requires no closing character.
