Consider the following code segment double num = 9 / 4

Consider the following code segment double num = 9 / 4; System.out.print(num); System.out.print(” “); System.out.print((int) num) What is printed as a result of executing the code segment?

A
2
2.0
2.25
2.0

The correct answer and explanation is :

Answer:

The output of the given code segment is:
2.0 2

Explanation:

Let’s analyze the code step by step:

double num = 9 / 4;
System.out.print(num);
System.out.print(" ");
System.out.print((int) num);

Step 1: Integer Division

The expression 9 / 4 consists of two integers (int type). In Java, when two integers are divided using the / operator, the result is an integer (not a decimal).

9 / 4 equals 2 (since integer division truncates the decimal part).

So, the expression 9 / 4 evaluates to 2, which is of type int.

Step 2: Assigning to a double Variable

double num = 9 / 4;

The result of 9 / 4 (which is 2) is assigned to the double variable num.
Since 2 is an integer, when stored in a double, it becomes 2.0.

Step 3: Printing `num`

System.out.print(num);

Since num is 2.0, this prints 2.0 to the console.

Step 4: Printing Space

System.out.print(" ");

This prints a space.

Step 5: Printing `(int) num`

System.out.print((int) num);

(int) num converts num (which is 2.0) into an integer.
This removes the decimal part and results in 2.
It prints 2.

Final Output

2.0 2

Correct Answer:

D) 2.0 2
