How can I insert arabic word to mysql database using java

Question

I have a java application, want to insert arabic words to mysql database, my code looks like

Connection con = null;
    String url = "jdbc:mysql://localhost/";
    String db = "students";
    String driver = "com.mysql.jdbc.Driver";
    try {
        Class.forName(driver);
        con = DriverManager.getConnection(url+db,"root","");
        Statement st = con.createStatement();
        String name = new String(txtName.getText().getBytes(), "UTF-8");
        int val = st.executeUpdate("insert into student(name, roll) VALUES('"+name+"','"+txtRoll.getText()+"')");
    } catch (Exception ex) {
        ex.printStackTrace();
    }

But it only insert '??????'. what can i do now?

Answer 1

add this variable after db variable declaration:

String unicode= "?useUnicode=yes&characterEncoding=UTF-8";

and then modify your line:

con = DriverManager.getConnection(url+db,"root","");

to

con = DriverManager.getConnection(url+db+unicode,"root","");
