![First of all this program has compilation errors.
Line 14: Wilma
Line 15:Fred, Pebbles, Barney, Bam-Bam, Betty
____________________________________
The Index of the ArrayList Starts from 0
Till line 11, the elements in the Array list are:
[Fred, Barney, Wilma, Betty]
In line 12,we are adding "BaM-Bam" at index 3
[Fred, Barney, Wilma, Bam-Bam, Betty]
In Line 13, we are adding "Pebbles" at index 1
[Fred, Pebbles, Barney, Wilma, Bam-Bam, Betty]
When this statement in the line 14 is executed
System.out.println(peopleList.remove(3));
This line will removes And displays Wilma
The line 15 will displays the elements in the array list:
Fred, Pebbles, Barney, Bam-Bam, Betty
In line 17 it is wrong atement.The program wont compile.
suppose if it is collections.sort(null) we will get null pointer exception.
Then line 19 will not get executed.
Solution
First of all this program has compilation errors.
Line 14: Wilma
Line 15:Fred, Pebbles, Barney, Bam-Bam, Betty
