SecureRandom setSeed() method in Java
The random object can be reseeded using the setSeed() method in the class java.security.SecureRandom. This method requires a single parameter i.e. the required seed byte array and it returns the reseeded random object.A program that demonstrates this is given as follows −Exampleimport java.security.*; import java.util.*; public class Demo { public static void main(String[] argv) { try { SecureRandom sRandom = SecureRandom.getInstance("SHA1PRNG"); String str = "Apple"; byte[] arrB = str.getBytes(); sRandom.setSeed(arrB); byte[] arrSeed = sRandom.getSeed(5); ...

In this article, we will learn about Stack & Queue structures in Python 3.x. Or earlier. Here we will discuss the working and modification within these data structures −This includes −Insertion operation (Push, Enqueue)Deletion operation (Pop, Dequeue)Display / Traversing OperationPrerequisites: List & List OperationsRelated Data Structure: List ManipulationRelated ImagesStackIn stacks, objects are stored one over another, and these objects get removed in the reverse order of the arrival i.e. LIFO concept is followed. LIFO means Last in First Out type arrangement is followed in the Stack data structure.Operations on a Stack −Addition / Appending of Element: This increases the stack ...
