ArrayList class provides both read and write functionalities.

Which means the size of ArrayList class can be increased or decreased according to requirement. Println( 'First Name:$ ') //list.Kotlin ArrayList class is used to create a dynamic array. Now print all the value with index number Note: in code, we use index number 4 because we just remove one element so the last index number is now 4. I am showing you those two ways by the value, we remove 'a' by index number, we remove index number 5 Now delete some data: we can remove by two ways. If we found the data and we print name found and if not we print name not found. Search in ArrayList: we make a search in our ArrayList. Now print all the element with the index number. Now print all the element by using a for loop. Now print the first element of this array list Now insert some value by calling add method you can take a look at this post of array section it will help you to understand today's topics easily.Ĭreate an instance of ArrayList class and make this variable as immutable by using val
