We will see how to reverse a linked list in java. LinkedList is a linear data structure where an element is a separate object with a data part and address part.
import java.util.*; class ReverseString { public static void main(String args[]) { //declaring string objects String str="",revStr=""; Scanner in = new Scanner(System.in); //input string System.out.print("Enter a string :"); str= in.nextLine(); //get length of the input s...
We are going to perform all of these operations: Shuffle() , Reverse(), Copy() , Rotate() and Swap(). First create classCrunchifyJava8ShuffleList.java. Next thing is to createList<String>and using Collection framework perform all operations. Kindly create below javaclassin yourEclipse environ...
We can use a for loop to reverse the contents of a string variable. See the below example code. using System; namespace reverse_string { class Program { static string Reverse(string text) { char[] charArray = text.ToCharArray(); string reverse = String.Empty; for (int i = charArray....
Another better solution/algorithm to avoid concatenation of string in every recursive call is to use another parameter that will take input i as an integer such that the function will give the reverse of the string starting from the index i to the end of the string. Java code for the follo...

In the above example, we first created aStreamof string and then collect the elements into aLinkedList. Since theLinkedListis a double-linked data structure in Java, we can iterate it in any direction: forward and backward. We preferred to loop over theLinkedListobject in the reverse direction...
