If you look closely this algorithm is similar to the algorithm we have earlier used toreverse an array in place. That's obvious because String is backed by character array in Java. If you know how to reverse an array in place then reversing a String is not different for you. What is m...

LinkedList is a linear data structure similar to arrays in Java. LinkedList items, on the other hand, are not kept in contiguous places like arrays; instead, they are linked together via pointers. Each LinkedList member has a reference to the next LinkedList element. TheLinkedList classis provide...

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 ...
