Question

Hello I have a ArrayList<String> with some strings. I would like to insert a string at a specific index, without loosing the string on that index. I know how to use list.add(index, string) but it replaces the string at the index with the new one.

For example I have this ArrayList:

index 0 => Orange
index 1 => Melon
index 2 => Apple
index 3 => Strawberry
index 4 => Pear
index 5 => Banana

Now I would like to add Cherry to index 2, so the result should be:

index 0 => Orange
index 1 => Melon
index 2 => Cherry 
index 3 => Apple
index 4 => Strawberry
index 5 => Pear
index 6 => Banana

Is there an easy way to do this, because it gives me headache.

Answer 1

Reference: ArrayList.add(index, element)

 void add(int index, E element)

Inserts the specified element at the specified position in this list.
Shifts the element currently at that position (if any) and any
subsequent elements to the right (adds one to their indices).

Should work on android too…
