I am struggling
### Example Code for Determining the Day of the Week #### Examples: ```java dayOfWeek(1) -> "Sunday" dayOfWeek(4) -> "Wednesday" ``` ### Your Answer: ```java public String dayOfWeek(int dayNum) { // Your code here } ``` In this example, the task is to define a method `dayOfWeek` that takes an integer input `dayNum` and returns the corresponding day of the week as a string. The integer values correspond to the days as follows: - 1 -> Sunday - 2 -> Monday - 3 -> Tuesday - 4 -> Wednesday - 5 -> Thursday - 6 -> Friday - 7 -> Saturday This method should be written in Java, as suggested by the syntax conventions of the provided code snippet. **Implementation Tips:** 1. **Function Declaration**: Start by declaring the function `dayOfWeek` with a public access modifier, returning a `String`, and taking an integer parameter `dayNum`. 2. **Mapping Day Numbers to Names**: You can use a switch-case structure to map the input integer to the corresponding day. 3. **Returning the Value**: Ensure that your function returns the correct day of the week as a string. Example implementation: ```java public String dayOfWeek(int dayNum) { switch(dayNum) { case 1: return "Sunday"; case 2: return "Monday"; case 3: return "Tuesday"; case 4: return "Wednesday"; case 5: return "Thursday"; case 6: return "Friday"; case 7: return "Saturday"; default: return "Invalid day number"; } } ``` This code will correctly match an integer input to its corresponding day of the week string and handle invalid inputs by returning "Invalid day number".
