PLEASE HELP ME FIX THIS CODE IN JAVA

1.15 LAB: Warm up: Basic output with variables This zyLab activity prepares a student for a full programming assignment. Warm up exercises are typically simpler and worth fewer points than a full programming assignment, and are well-suited for an in-person scheduled lab meeting or as self-practice. A variable like userNum can store a value like an integer. Extend the given program as indicated. 1. Output the user's input. (2 pts) 2. Output the input squared and cubed. Hint: Compute squared as userNum * userNum. (2 pts) 3. Get a second user input into userNum2, and output the sum and product. (1 pt) Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs. Enter integer: 4 You entered: 4 4 squared is 16 And 4 cubed is 64!! Enter another integer: 5 4+5 is 9 45 is 20 444740.2644432.q32qy7 OutputWithVars.java \begin{tabular}{l|l} 1 & \\ 2 & import java.util.*; \\ 3 & \\ 4 & public class Main \\ 5 & \{ \\ 6 & public static void main(String[] args) \\ 7 & int userNum, userNum2; \\ 8 & Scanner sc = new Scanner(System.in); \\ 9 & System. out.println("Enter integer: "); \\ 10 & userNum = sc.nextInt(); \\ 11 & System. out.println("You entered: "+userNum); \\ 12 & System. out.println(userNum+" squared is "+userNum*userNum); \\ 13 & System. out.println("And "+userNum+" cubed is "+userNum*userNum*userNum+"!!"); \\ 14 & System. out.println("Enter another integer: "); \\ 15 & userNum2 = sc.nextInt(); \\ 16 & System. out.println(userNum+" + "+userNum2+" is "+ (userNum+userNum2)); \\ 17 & System. out.println(userNum+" * "+userNum2+" is "+ userNum*userNum2); \\ 18 & \} \\ 19 & ? \end{tabular} OutputWithVars.java:4: error: class Main is public, should be declared in a file named Main. public class Main 1 error
