In this example, we have a list of integers that we want to sort in ascending order. We use theCollections.sort()method to sort the list, and then print the sorted list to the console. The output shows the list sorted in ascending order. This is a basic way to sort a list in Jav...
Output: 12345 In this example, we create a list of integers usingArrays.asList(), namednumberList. TheforEach()method is then applied to this list, taking a lambda expression as its argument. The lambda expression(item -> System.out.println(item))serves as the action to be performed on...
