To iterate over a collection using JSTL in a JSP page, you can use the `` tag provided by the JavaServer Pages Standard Tag Library. This tag allows you to easily loop over a collection and display its elements on the page.

Below is an example code snippet demonstrating how to achieve this:

```html

Displaying Collection Elements

${element}

```

In the above code:
- The `` tag is used to iterate over the `collection` and assign each element to the `element` variable.
- The `items` attribute in the `` tag specifies the collection to iterate over.
- `${element}` is used to display each element within the loop.

By utilizing JSTL's `` tag in a JSP page, you can efficiently iterate over a collection and display its elements, making your code more structured and maintainable.
