Remove Items From ArrayList in Kotlin

Another way to change the data in an ArrayList is with the .removeAt() method.

.removeAt() takes one parameter which represents an index and removes the element placed at that index:

val threeArr = mutableListOf(1, 4, 6)

// Remove second element:
threeArr.removeAt(1)

// threeArr has now the value [1, 6]

// Remove first element:
threeArr.removeAt(0)

// threeArr has now the value [6]
