Answer 1

Corrected question:

Give the output of the following program segment: double x = 2.9 , y = 2.5 ;

System.out.println(Math.min (Math.floor(x),y));

System.out.println(Math.max(Math.ceil(x),y));

Answer:

==> 2.0

==> 3.0

Explaination:

Here we have been provided with the values of x and y.

Math.floor returns us the largest integer which is less than or equal to that given argument.

==> Math.min (Math.floor (2.9)2.5)

Largest integer would be 2.0

==> Math.min (2.0 , 2.5)

Math.min returns us the smallest of the given two arguments.

As 2.0 is less than 2.5. So, answer would be 2.0

==> 2.0

________________

As we know that Math.ceil returns us the smallest integer which would be greater than or equal to the given argument.

==> Math.max (Math.ceil(2.9) , 2.5)

Smallest integer would be 3.0

As again we know that Math.max returns us the largest integer of the given two arguments.

Largest integer between 2.5 and 3.0 is 3.0

==> 3.0

Return type:

• Math.ceil's return type is double
• Math.max's return type is Same as argument
• Math.min's return type is also same as argument
• Math.floor's return is double.
