We will use a lambda expression to achieve this and pass it as an argument to the forEach method.Following are the steps to reverse a string in an ArrayList using lambda ?Step 1 - START Step 2 - We import the required packages. Step 3 - In the main function, we define an ?
This method uses Array.Reverse to reverse the order of the elements, such that the element at ArrayList [i], where i is any index within the range, moves to ArrayList [j], where j equals index + index + count - i - 1. This method is an O(n) operation, where n is Count. Appli...

Thread.sleep Example In Java Let’s now move on to an example that demonstrates the sleep method. Here, we have a thread class that has a run () method. In the run () method we call ‘Thread.sleep (1000)’. Then in the main function, we create two instances of this thread i.e...
The method creates a newly created mergedList from an ArrayList. It iterates up to the maximum length of the two lists using a for loop. In each iteration, it checks if the index is within the bounds of each list. It adds the corresponding element to the mergedList using the add() ...
