In Java, what is the result of truncating a floating-point number when cast to an integral type?

Rounding up
Rounding down
It gets converted to the nearest integer
Truncates the decimal part

The correct answer is: Truncates the decimal part

When a floating-point number is cast to an integral type in Java, all decimal places are truncated. This means the number is rounded down to the closest integer without taking into account the decimal part. Therefore, both options A and B are incorrect because the number is not rounded up or down, it is simply truncated. Option C is also incorrect because the number is not converted to the nearest integer, it is simply truncated.
