Question 3
Which of the following expressions produce a value of type int? Mark all that apply.
1 point
2 + 2
Integer.parseInt("2")
2 + 2.0
7 / 3
11 * (int) 0.25
11*(int) 0.25
This expression produces a value of type int.
The expressions that produce a value of type int are:
1. 2 + 2
2. Integer.parseInt("2")
3. 7 / 3
4. 11 * (int) 0.25
To determine which of the following expressions produce a value of type int, we need to understand the data types and operations involved.
Let's go through each expression:
1. 2 + 2
This expression involves adding two integers, so the result will also be an integer. Therefore, this expression produces a value of type int.
2. Integer.parseInt("2")
The Integer.parseInt() method is used to convert a String to an int. In this case, we are converting the string "2" to an int. So, this expression also produces a value of type int.
3. 2 + 2.0
In this expression, we are adding an integer (2) with a floating-point number (2.0). Whenever we perform arithmetic operations involving a floating-point number, the result will be a floating-point number. Therefore, this expression does not produce a value of type int.
4. 7 / 3
This expression involves integer division, where the result will be the quotient without any decimal places. Since both 7 and 3 are integers, the division operation will produce an integer value. So, this expression produces a value of type int.
5. 11 * (int) 0.25
Here, we are multiplying an integer (11) with a casted value (0.25 casted to int). The cast operation explicitly converts the floating-point number 0.25 to an int. As a result, this expression also produces a value of type int.
Based on the explanations above, the expressions that produce a value of type int are:
- 2 + 2
- Integer.parseInt("2")
- 7 / 3
- 11 * (int) 0.25
Therefore, marking all these options would be correct.
