How are floating-point numbers stored in Java?

Using Integer data type
In binary format
As objects
Using IEEE754 standard

The correct answer is: Using IEEE754 standard

Floating-point numbers in Java are stored using the IEEE754 standard. This standard specifies the format for representing floating-point numbers in binary, which allows for more precise values to be stored than with an Integer data type. Option A, using Integer data type, is incorrect because it only allows for whole numbers to be stored. Option C, as objects, is incorrect because although floating-point numbers can be stored as objects, they are stored as objects following the IEEE754 standard. Finally, option B, in binary format, is not necessarily incorrect as this is the format specified by the IEEE754 standard, but it is not as complete an answer as option D, which specifies the specific standard used for storing floating-point numbers in Java.
