### Understanding Return Statements in Java #### Example 1: ```java public static double getPrice() { system.out.printf("%nWhat is the price? "); return input.nextDouble(); } ``` **Question:** The return statement is returning from a ___________. Options: - a. method call - b. literal - c. variable - d. class #### Explanation: In this example, `return input.nextDouble();` returns a value obtained from a method call (`input.nextDouble()`). --- #### Example 2: ```java public static double getPrice() { return price; } ``` **Question:** The return statement is returning from a ___________. Options: - a. method call - b. literal - c. variable - d. class #### Explanation: In this example, `return price;` uses a variable (`price`) to return a value. --- #### Example 3: ```java public static double getPrice() { return 10.25; } ``` **Question:** The return statement is returning from a ___________. Options: - a. method call - b. literal - c. variable - d. class #### Explanation: In this example, `return 10.25;` directly returns a literal value (`10.25`). --- These examples illustrate different ways a return statement in Java can derive the value it returns. Understanding these concepts is fundamental in programming, helping improve code efficiency and readability.
