Why does getting JDBC Connection need Reflection? [duplicate]

This question already has an answer here:

• Why we use Class.forName(“oracle.jdbc.driver.OracleDriver”) while connecting to a DataBase? 7 answers

The code as following:

try{
    Class.forName("com.mysql.jdbc.Driver");
    Connection c=DriverManager.getConnection(url);
}catch(Exception e){
    System.err.println("no class!");
}

why geting Connection by JDBC need Class.forName(): the Reflection mechanism？Can import com.mysql.jdbc.Driver replace it？
