Explanation

In Java, the valueOf() method is commonly used to convert String representations to Number types (Integer.valueOf(), Long.valueOf(), Double.valueOf(), etc.). Options like toNumber() and conString() are not standard Java methods for this purpose.

AI explanation

To convert a String to a Number in a Java program, the function used is the valueOf() function.

Let's go through each option to understand why it is correct or incorrect:

Option A) toNumber() - This option is incorrect because there is no built-in function in Java called toNumber().

Option B) conString() - This option is incorrect because the function name does not suggest any conversion from a String to a Number.

Option C) valueOf() - This option is correct because the valueOf() function is a built-in function in Java that can be used to convert a String to a Number.

Option D) None of the Above - This option is incorrect because the correct answer is option C) valueOf().

The correct answer is C) valueOf(). This option is correct because it is the function used to convert a String to a Number in a Java program.
