用oracle在java中执行简单CRUD出错

Question

伙计们。 下面的代码不起作用。指责错误。

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;

public class Main {
    public static void main(String[] args) throws Exception
    {
        Class.forName("oracle.jdbc.driver.OracleDriver");
        Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XEPDB1","hr","hr");
        Statement st = con.createStatement();
        st.executeUpdate("CREATE TABLE student(rno number, name varchar(20),branch varchar2 (20))");
        st.close();
        con.close();
    }
}

错误：
