Which data type is better?

[Kaleeswaran Karuppusamy]

I declared ALL field as a String in action form,If we need integer field,i Use only String instead of int,reason is while we declared integer in action form,in jsp side the field associated particular field(text field in jsp) display zero defualt, and further we need steps to clear the text field in design side.

My question is my friend said dont use String variable it takes more memory rather than int ,please suggest me String or Integer?

[Merrill Higginson]

You're right to use only Strings in your ActionForm. Struts specifically recommends it.

Your friend is right that it uses more memory, but so what? We're talking about one or two bytes difference, and in these days of cheap memory, that is not significant.

Yep...Struts 1.x likes Strings. I do use types like long or int to represent index values of lists and for some id values that are passed along as hidden fields. I use Strings for all editable fields.
