java - Difference Between dot operator and brackets in jsp el

Question

I have so class:

public class MyClass{
   String name;
   Map map;
   int [] arrInt;
//get  set
}

I create Object:

MyClass  mc = new MyClass  ();

In jsp I can write so code:

${mc.name}

and it the same as

${mc["name"]}

There are exist differencies between dot operator and bracket operator ?

Answer 1

They have exactly the same meaning. The dot style is often easier to read. You need the bracket style if the index is going to be given by an expression (e.g. mc[name] instead of mc["name"]).
