Error in insert data using keyboard on JDBC

In JDBC, I want to insert data using input from the keyboard.

As a result of finding the method, I came to know the scanner and wrote the code as follows.

package DB;

import java.sql.SQLException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
import java.util.Scanner;

class insert{

	Connection con;

	Statement stmt;

	Scanner scan = new Scanner(Syetem.in);

	public insert() {
		try {
			Class.forName("oracle.jdbc.driver.OracleDriver");
			String url = "jdbc:oracle:thin:@localhost:1521:orcl";
			con = DriverManager.getConnection(url,"scott","1234");
			stmt = con.createStatement();
		} catch(ClassNotFoundException ce) {
			System.out.println(ce.getMessage());
		} catch(SQLException se){
			System.out.println(se.getMessage());
    	}
	}

	public void disconnect() throws SQLException{
		if (stmt!=null) stmt.close();
		if (con!=null) con.close();
	}

	public void insert() throws SQLException{
		System.out.println("name:")
		String employee_name=scan.next();

		System.out.println("domain:")
		String street=scan.next();

		System.out.println("country:")
		String city=scan.next();

		String sql="insert into information values('"+name+"', '"+domain+"', '"+country+"')";

		int n=stmt.executeUpdate(sql);
	}

}

But it didn't run and got an error ...
The default method cannot be found in the class. Define a default method in the following format. public static void main (String [] args)

Where should I put the main function to fix the error?

What is the problem? The name of the table to be inserted is 'information'.

Any help would be greatly appreciated

• Because JDBC is not yet familiar, if possible, if you write a full query including a connection as in the above query, I would be very grateful.

*my oracle version is 11g

For your code to run you need to provide a method that works as an entry point for your program, that method has the signature public static void main(String[] args) besides that, your class should be named Insert with capital I first because thats de standard y second because you have a method called insert, you will need to have something like this:

public class Insert {
  public Insert() { 
  ...    
  }

  public void disconnect() throws SQLException {
  ...
  }

  public void insert() throws SQLException {
  ...
  }

  public static void main(String[] args) {
    new Insert().insert();
  }
}
