The java.util List sort method is a built-in function in the Java programming language that is used to sort a list of elements in ascending order. This method sorts an array, a list, or any other collection of elements in increasing order.
For instance, if you have a list of integers that you want to sort in ascending order, you can use the following code snippet:
List numbers = Arrays.asList(4,1,3,2,5); Collections.sort(numbers); System.out.println(numbers);
In this code snippet, we declare a List of integers with the values 4, 1, 3, 2, and 5, and then we use the sort method from the Collections utility class to sort them in ascending order. The output of the program will be the sorted list {1, 2, 3, 4, 5}.
Another example is sorting a list of strings, like this:
List strings = Arrays.asList("banana", "apple", "orange"); strings.sort(Comparator.naturalOrder()); System.out.println(strings);
In this case, we use the sort method directly on the list of strings and pass a Comparator to sort them in natural order. The output of the program will be the sorted list {"apple", "banana", "orange"}.
The java.util List sort method is part of the standard Java library, which is included in the java.util package.
