import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class Test {

    public static void main(String[] args) throws ClassNotFoundException, SQLException {
        //1.加载驱动
        Class.forName("oracle.jdbc.driver.OracleDriver");
        //2.获得数据库连接
        String url="jdbc:oracle:thin:@localhost:1521:orcl";
        Connection conn=DriverManager.getConnection(url,"system","toor");
       System.out.println("连接成功");
        //3.执行sql语句
  Statement st=conn.createStatement();
       String sql="insert into student values(5,‘nama‘,‘man‘)";
       st.execute(sql);
       System.out.println("插入成功");
       st.close();
        conn.close();
    }
