Question
In Java, what type of casting is converting a double to an int?*
Solution
The type of casting that is used to convert a double to an int in Java is known as "Narrowing Casting" or "Explicit Casting".
Here are the steps to do it:
- Declare a double variable. For example:
double myDouble = 9.78; - Then, you can cast the double to an int. To do this, you place the type you want to cast to in parentheses to the right of the equals sign, and then the variable you want to cast to the left of the equals sign. For example:
int myInt = (int) myDouble; - Now,
myIntwould be 9, because when you cast a double to an int, the number is simply truncated, not rounded. So, 9.78 becomes 9.
Remember, in Java, narrowing casting must be done manually because you are trying to fit a larger primitive type (double) into a smaller one (int), which could lead to data loss.
