I have a problem when I enter data from the application to mysql database, it appears in the form of "????" However, when I enter data via "phpmyadmin" the data appears normally well the problem is when i enter data via application , not related with database any way i tried to change the encode of database and the table and the fields inside the tables
here the insert query in my application
public static void dbConnect() {
try{
Class.forName(DRIVER);
connector = DriverManager.getConnection(DATA_BASE_BATH, "root", "");
insert = connector.prepareStatement("INSERT INTO students VALUES (?,?,?,?)");
}
public static void insert(int id , String name , String special , double gpa){
dbConnect();
try{
insert.setInt(1, id);
insert.setString(2, name);
insert.setString(3,special);
insert.setDouble(4,gpa);
insert.execute();
}
catch(SQLException e){
System.out.println(e.getMessage());
}
}
here the image to understand the problem
-the first row is the data entry from the application
-and the second row is the data entry manually from the phpmyadmin
