One of the common Java coding interview questions is towrite a program to reverse a String in place in Java, without using additional memory. You cannot use any library classes or methods likeStringBuilderto solve this problem. This restriction is placed becauseStringBuilderandStringBufferclass define...

A 2D list can be iterated in one of the two methods that follow Using Loops Using iteratorMethod 1: Employing LoopsThere are two ways for you to traverse over a 2D list (a list of lists).The first is the usage of a nested for-each loop. For this, we must first retrieve the 2D ...
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 ...
