    Default need help on my code

    well i've been trying to fix my code but i dont know what is wrong. im just a beginner in java and was lookong for help on trying to make this program...

    Here is my code:

    File 1
    public class Pet1{
     
    public void displayCourse(String courseName){
    System.out.println("List of Student");
    System.out.println(" 1. Joseph Rosopa");
    }
     
    public void displayCourse2(String couseName2){
    System.out.println("Total Average");
    }
    }

    The error in file 1 is okay since i always get the same error on the past program i used to run.

    File 2
    import java.util.Scanner;
     
    public class File2{
     
    public static void main(String[]args);
    Scanner user_input= = new Scanner (System.in);
    Pet1 myObject = new Pet1();
    System.out.print("Enter Quiz 1: ");
    String courseName = user_input.nextLine();
    System.out.println();
    myObject.displayCourse(courseName);
     
    System.out.print("Enter Quiz 2: ");
    String courseName = user_input.nextLine();
    System.out.println();
    myObject.displayCourse(courseName);
     
    System.out.print("Enter Quiz 3: ");
    String courseName = user_input.nextLine();
    System.out.println();
    myObject.displayCourse(courseName);
     
    }
    }

    i dont know what is wrong
    Can you explain?
    Does the code compile? If not copy and paste the errors here.
    Does the code execute without errors? If not same as above.

    Does the code do what you want? If not explain.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.

    Copy any relevant information about the program here on the forum as text.
    If you don't understand my answer, don't ignore it, ask a question.

    Sorry, I missed your explanation of what is wrong with the program.
    Copy the program's output and add comments to it saying what the problem is.


    Please copy and paste the console window here instead of images. There is no way to copy the contents of an image.
    To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.
    If you don't understand my answer, don't ignore it, ask a question.

    It looks like the compiler thinks all the code in the error messages is not inside of a method.
    Check that you have properly defined the methods. They all require {}s to surround the code that belongs to a method.
    See the tutorial: Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

    Read the tutorial about how to write a method.
    Then look at the code with all the problems and see if you are following the rules for writing a method.
    The error is before the line with the first error. Line 6:
    Pet2.java:6: error: illegal start of expression

    If needed, start over and write the code again being sure to follow the rules for writing a method.
    Write a few lines of code, compile, fix the errors, add a few more lines, compile, fix the errors, add a few more lines, etc
    If you don't understand my answer, don't ignore it, ask a question.
