Servlet code for validating user
Stack memory size is very less compared to Heap memory.
As soon as method ends, the block becomes unused and become available for next method.
mode, which allows you to process HTML5 files with features such as standalone (not closed) tags, tag attributes without a value or not written between quotes.
In order to process files in this specific mode, Thymeleaf will first perform a transformation that will convert your files to well-formed XML files which are still perfectly valid HTML5 (and are in fact the recommended way to create HTML5 code).
Second, the value attribute in the submit button makes it display a text in English, but we’d like it to be internationalized. Specifying an assignment inside an attribute’s value can be very practical, but it is not the most elegant way of creating templates if you have to do it all the time. And that’s why in fact attributes, which append (suffix) or prepend (prefix) the result of their evaluation to the existing attribute values. attribute by writing its name after the iter variable itself, separated by a comma.
For example, you might want to store the name of a CSS class to be added (not set, just added) to one of your buttons in a context variable, because the specific CSS class to be used would depend on something that the user did before. The Standard Dialect includes attributes that allow you to set these attributes by evaluating a condition, so that if evaluated to true, the attribute will be set to its fixed value, and if evaluated to false, the attribute will not be set: So far we have created a home page, a user profile page and also a page for letting users subscribe to our newsletter… Shouldn’t we build a product list to let visitors know what we sell? As happens to the iter variable, the status variable will only be available inside the fragment of code defined by the tag holding the standard, that establishes those values as default for those attributes (remember that our template didn’t set a value for them).
The main goal of Thymeleaf is to provide an elegant and well-formed way of creating templates.
