sort() method for ArrayList or LinkedList:

The Collections.sort(list) is used to sort the list of ArrayList or LinkedList. The smallest value is present in the first element and the largest value is present in the list.

Collections.sort(list);

For Example:

LinkedList<String> l = new LinkedList<>();

l.add("C");

l.add("Python");

l.add("Java");

Colections.sort(l);

Explanation:

• Create an object for LinkedList for “l” and add the values into list such as C, Python, and Java. Then, to sort the list the following statement is used:

Collections.Sort(l)

• The above statement sorts the list and gives the result as C, Java, and Python.

Therefore, “Collections.sort(list)” is used to sort the ArrayList or LinkedList...
