Question

Which of the following would compile without error? A. int a = Math.abs(-5); B. int b = Math.abs(5.0); C. int c = Math.abs(5.5F); D. int d = Math.abs(5L);

Answer 1

int a = Math.abs(-5)

Step-by-step explanation:

Math.abs() is the function which gives the absolute value of the integer.

syntax:

Math.abs(int name);

the argument enter must be integer(int).

int b = Math.abs(5.0): here, 5.0 is not the integer, it is float. So, it gives error.

int c = Math.abs(5.5F): here, 5.5F is not the integer, it is float. So, it gives error.

int d = Math.abs(5L): L stand for long but it is not int. So, it also gives error.

Therefore, the correct result is int a = Math.abs(-5), -5 is integer.
