Question

Which of the following expressions produce a value of type int?

Answer 1

2 + 2
Integer.parseInt("2")
2 + 2.0
7 / 3
11 * (int) 0.25

Answer 2

well, clearly 2+2 and parseint() and casting as (int) do the job
also 7/3, since java does integer division

the java documentation is very complete. You would do well do read it and refer to it often.

Answer 3

2 +2
