To covert a number from one data type to another, you use the . . . . . . . .

Convert class
Parser
Literal constant
Object

The correct answer is: A. Convert class

A Convert class is a class that provides methods for converting data from one type to another. It is a built-in class in Java and can be used to convert numbers, strings, and other data types.

A Parser is a program that converts data from one format to another. It is not a built-in class in Java and must be imported from a library.

A Literal constant is a value that is written directly into the code. It is not a class and cannot be used to convert data.

An Object is a data structure that contains data and methods. It is not a class and cannot be used to convert data.

Here is an example of how to use the Convert class to convert a number from one data type to another:

int number = 10;
double convertedNumber = Convert.toDouble(number);

In this example, the number 10 is converted from an integer to a double.
