What are the possible outcomes of following code? Explain.

Question

a) 1
b) 2
c) 3
d) 0

System.out.print((int)(Math.random()*3));

Answer 1

Math.random() returns a double from 0.0 to 0.9. This return value *3 ranges from 0.0 to 2.7.
The cast to int simply cuts off the value without rounding, so values from 0 to 2 are possible.
So a), b) and d) is correct.
