FAQs on #10.3 Kotlin Android Tutorial: MAP and HASH MAP Mutable and Immutable Collections PART-3 Video Lecture - Kotlin Tutorial for Beginners: Learn Kotlin in easy language - Back-End Programming
| 1. What is the difference between a mutable map and an immutable map in Kotlin? |  |
Ans. In Kotlin, a mutable map is a collection that allows modifications, such as adding, updating, or removing elements, after its creation. On the other hand, an immutable map is a read-only collection where elements cannot be modified once the map is created.
| 2. How can I create an empty mutable map in Kotlin? | |
Ans. To create an empty mutable map in Kotlin, you can use the mutableMapOf() function. Here's an example:
```
val mutableMap = mutableMapOf<String, Int>()
```
This creates an empty mutable map with keys of type String and values of type Int.
| 3. How can I add elements to a mutable map in Kotlin? | |
Ans. You can add elements to a mutable map in Kotlin using the put() function. Here's an example:
```
mutableMap.put("key", value)
```
This adds an element with the specified key and value to the mutable map.
| 4. How can I retrieve the value associated with a specific key in a map in Kotlin? | |
Ans. To retrieve the value associated with a specific key in a map in Kotlin, you can use the get() function. Here's an example:
```
val value = map.get("key")
```
This retrieves the value associated with the "key" in the map and assigns it to the variable "value".
| 5. Can I convert a mutable map to an immutable map in Kotlin? | |
Ans. Yes, you can convert a mutable map to an immutable map in Kotlin using the toMap() function. Here's an example:
```
val immutableMap = mutableMap.toMap()
```
This creates an immutable map from the mutable map. Any modifications made to the mutable map after conversion will not affect the immutable map.
