Read data from HashMap using JSTL tag in JSP without using for each or for loop

Question

I want to read data from a hash map in JSP, but without the use of JSTL or a for loop. How can I do this?

Answer 1

You need to know the keys beforehand.

${map.key}

The above gets the value of map.get("key").

---

Or if the key contains dots

${map['key.with.dots']}

This gets the value of map.get("key.with.dots").

---

Or if it's a dynamic key

${map[dynamicKey]}

This gets the value of map.get(dynamicKey).
