Question

5

Consider the following code segment.
double x = (int) (5.5 - 2.5);
double y = (int) 5.5 - 2.5;
System.out.println(x - y);
What is printed as a result of executing the code segment?
А
-1.0
B



-0.5
С
0.0
D
0.
1.0

Answer 1

The given Java code segment prints out 0.5 as a result of subtracting double y (2.5) from double x (3.0), after casting operations are performed on the values.

Step-by-step explanation:

The code segment in question involves casting and arithmetic operations in Java. The first line, double x = (int) (5.5 - 2.5);, involves casting the result of the subtraction, which is 3.0, to an integer, resulting in x being 3.0 because when a double is cast to an int, the decimal part is truncated.

The second line, double y = (int) 5.5 - 2.5;, first casts 5.5 to an int, resulting in 5, and then subtracts 2.5, ending with y equal to 2.5. The System.out.println(x - y); line prints out the result of the subtraction of y from x, which is 3.0 - 2.5, resulting in 0.5. Therefore, the output of the code segment is 0.5.

Answer 2

The output is 0.5

Step-by-step explanation:

Analyzing the code line by line

Line 1: double x = (int) (5.5 - 2.5);

This converts the result of 5.5 - 2.5 to int

i.e 5.5 - 2.5 = 3.0

3.0 is then converted to int; which is 3

Hence,

x = 3

Line 2: double y = (int) 5.5 - 2.5;

This converts 5.5 to int; i.e 5

Then

y = 5 - 2.5

y = 2.5

Line 3: System.out.println(x - y);

This prints the result of x - y

x - y = 3 - 2.5

x - y = 0.5

Hence;

The output is 0.5
