Chapter 10: Problem 16

Assume that a program has the following declarations: double number \(=9.47\) String str: Write a statement that assigns a string representation of the number variable to str.

Short Answer

Expert verified
Answer: You can use the Double.toString() method to convert the double variable to a string and assign it to the String variable. For example, for a double variable "number" and a String variable "str", you can use the following code statement: ```java str = Double.toString(number); ```

Step by step solution

01

Identify the built-in method for converting numbers to strings

Java provides a built-in method Double.toString() which is used to convert a double (or any other numeric value) to its corresponding string representation. We need to use this method to convert the given "number" variable to a string.
02

Assign the string representation of 'number' to 'str'

To assign the string representation of 'number' to 'str', we simply call the previously mentioned method and pass 'number' as an argument. Here's the code statement: ```java str = Double.toString(number); ``` Now, 'str' will store the string representation of the number '9.47'.
