![]() Inserts the specified element at the specified position in this Vector.Īppends all of the elements in the specified Collection to the end of this Vector, Methods inherited from class Īppends the specified element to the end of this Vector. It returns the position of the element from the top of the stack. It determines whether an object exists in the stack. Pushes an element on the top of the stack. ![]() An ‘EmptyStackException’Īn exception is thrown if we call pop() when the invoking stack is empty. Removes and returns the top element of the stack. Returns the element on the top of the stack, but does not remove it. ![]() It returns true if nothing is on the top of the stack. The Stack class also provides several constructors for creating a stack with a specified initial capacity or by copying an existing stack. The Stack class provides several other methods for manipulating the stack, such as peek() to retrieve the top element without removing it, search() to search for an element in the stack and return its position, and size() to return the current size of the stack. The below example creates an empty Stack. In order to create a stack, we must import package and use the Stack() constructor of this class. RandomAccess: This is a marker interface used by List implementations to indicate that they support fast (generally constant time) random access.List: The List interface provides a way to store the ordered collection.The Collection interface is used to pass around collections of objects where maximum generality is desired. Collection: A Collection represents a group of objects known as its elements.Iterable: This interface represents a collection of objects which is iterable - meaning which can be iterated.Cloneable: This is an interface in Java which needs to be implemented by a class to allow its objects to be cloned.Serializable: It is a marker interface that classes must implement if they are to be serialized and deserialized.Software Engineering Interview Questions.Top 10 System Design Interview Questions and Answers.Top 20 Puzzles Commonly Asked During SDE Interviews.Commonly Asked Data Structure Interview Questions.Top 10 algorithms in Interview Questions.Top 20 Dynamic Programming Interview Questions.Top 20 Hashing Technique based Interview Questions.Top 50 Dynamic Programming (DP) Problems.Top 20 Greedy Algorithms Interview Questions.Top 100 DSA Interview Questions Topic-wise.
