### Matching Code Examples with Return Value Usage

This section provides three code snippets, each demonstrating a different way of using the return value from a `max` function, presumed to find and return the maximum of two numbers. Match each snippet to the appropriate usage:

1. **Code Example:**

   ```java
   int maximum = max(num1, num2);
   ```

   **Usage:** This example assigns the return value of the `max` function to a variable called `maximum`.

2. **Code Example:**

   ```java
   System.out.printf("The maximum value is %d.", max(num1, num2));
   ```

   **Usage:** This example directly uses the return value of the `max` function as an argument in a print statement.

3. **Code Example:**

   ```java
   if(max(num1, num2) > 90)
   {
       //statements
   }
   ```

   **Usage:** Here, the return value of the `max` function is used in a conditional statement to compare whether it exceeds the value of 90. If true, the associated block of code (denoted by `//statements`) is executed. 

Each example illustrates a common pattern of return value utilization in programming, showcasing assignment, direct usage in expressions, and conditional evaluation.

**Code Example and Return Value Usage**

The image shows a prompt to match code examples with their respective usages of return values.

**Code Examples:**

1. `int maximum = max(num1, num2);`
2. `System.out.printf("The maximum value is %d.", max(num1, num2));`
3. 
   ```java
   if(max(num1, num2) > 90) {
       // statements
   }
   ```

**Return Value is Used:**

- There is a dropdown with the following options:
  - null
  - in an output statement
  - as part of a test expression
  - in an assignment statement

**Explanation:**

- The first line assigns the result of `max(num1, num2)` to a variable, so the return value is used "in an assignment statement."
- The second line uses `max(num1, num2)` in a `printf` statement, categorizing it as "in an output statement."
- The third example uses `max(num1, num2)` in a conditional statement, which makes it "as part of a test expression."
