Connection con=DriverManager.getConnection("jdbc:odbc:DataBase");
System.out.println("Sucessfully Connected ");
Statement st= con.createStatement();
ResultSet rs= st.executeQuery("Select empid,ename from emp");

That does not look like a valid connection string. You need to use something closer to this

String connectString = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=" + projectDirectory + filename;

try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String url = "jdbc:odbc:Driver={Microsoft Access Driver "//makes it use access driver
                    + "(*.mdb, *.accdb)};DBQ= c:\\StudentDatabase.accdb";//gets database at its path
            con = DriverManager.getConnection(url);//creates connection 
Statement st= con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);       
String     SQL = "Select empid,ename from emp";
ResultSet rs= st.executeQuery(SQL);
 
while(rs.next()){
System.out.print(rs.getString());
System.out.println(rs.getString());
}
        } catch (SQLException e) {

            JOptionPane.showMessageDialog(rootPane, "An error has occured: " + e.getMessage(), "Error", JOptionPane.ERROR_MESSAGE);
        } catch (ClassNotFoundException ce) {
            JOptionPane.showMessageDialog(rootPane, "An error has occured: " + ce.getMessage(), "Error", JOptionPane.ERROR_MESSAGE);
        }
    }

hope that works, make sure your sql query works, and change database name from 'DBQ= c:\\StudentDatabase.accdb'

System.out.println(rs.getString(1));
System.out.println(rs.getString(2));

error correction in above code
