In this article, we will learn to iterate list in our Java application. There are many ways to iterate list. List can be iterated using its forEach method that will use lambda expression as an argument.
// ListIterator - traverse a list of elements in either forward or backward order // An iterator for lists that allows the programmer to traverse the list in either direction, modify the list during iteration, // and obtain the iterator's current position in the list. System.out.println("...
Inside the loop, System.out.println(fruit) prints each fruit to the console. The enhanced for loop handles the iteration, making the code concise and easy to read. This method is particularly useful when you only need to traverse the elements of a collection sequentially without requiring the ...
