System.ListException: List index out of bounds: 6

Question

list<integer> mynums = new list<integer>();
mynums.add(10);
mynums.add(20);
mynums.add(30);
mynums.add(20);
mynums.add(10);
mynums.add(5,60);
system.debug('list values'+mynums);

This is my code,when i want to insert an other number with index 5 it is throwing an error as shown above. Help me out.............

Answer 1

First make List<Integer> instead of list it is error.

second since index 5 value is not initiated yet you cannot push value directly at 5 index try to push it at 4 and it will work.

hope this helps.
