Stack size() method in Java with Example Last Updated : 24 Dec, 2018 Comments Improve Suggest changes Like Article Like Report The Java.util.Stack.size() method in Java is used to get the size of the Stack or the number of elements present in the Stack. Syntax: Stack.size() Parameters: The method does not take any parameter. Return Value: The method returns the size or the number of elements present in the Stack. Below programs illustrate the Java.util.Stack.size() method: Program 1: Stack with string elements. Java // Java code to illustrate size() import java.util.*; public class StackDemo { public static void main(String args[]) { // Creating an empty Stack Stack<String> stack = new Stack<String>(); // Use add() method to add elements into the Stack stack.add("Welcome"); stack.add("To"); stack.add("Geeks"); stack.add("4"); stack.add("Geeks"); // Displaying the Stack System.out.println("Stack: " + stack); // Displaying the size of Stack System.out.println("The size is: " + stack.size()); } } Output: Stack: [Welcome, To, Geeks, 4, Geeks] The size is: 5 Program 2: Stack with integer elements. Java // Java code to illustrate size() import java.util.*; public class StackDemo { public static void main(String args[]) { // Creating an empty Stack Stack<Integer> stack = new Stack<Integer>(); // Use add() method to add elements into the Stack stack.add(10); stack.add(15); stack.add(30); stack.add(20); stack.add(5); // Displaying the Stack System.out.println("Stack: " + stack); // Displaying the size of Stack System.out.println("The size is: " + stack.size()); } } Output: Stack: [10, 15, 30, 20, 5] The size is: 5 Comment More infoAdvertise with us Next Article Stack size() method in Java with Example C code_r Follow Improve Article Tags : Java Java-Collections Java - util package Java-Functions Java-Stack +1 More Practice Tags : JavaJava-Collections Similar Reads Stack peek() Method in Java The java.util.Stack.peek() method in Java is used to retrieve or fetch the first element of the Stack or the element present at the top of the Stack. The element retrieved does not get deleted or removed from the Stack. Syntax:STACK.peek()Parameters: The method does not take any parameters.

The method is of boolean type and returns true if the stack is empty else false. Syntax: STACK.empty() Parameters: The method does not take any parameters. Return Value: The method returns boolean true if th 4 min read Stack search() Method in Java The java.util.Stack.search(Object element) method in Java is used to search for an element in the stack and get its distance from the top. This method starts the count of the position from 1 and not from 0. The element that is on the top of the stack is considered to be at position 1. If more than o 2 min read Stack removeElementAt() method in Java with Example The Java.util.Stack.removeElementAt(int index) method is used to remove an element from a Stack from a specific position or index. In this process the size of the Stack is automatically reduced by one and all other elements after the removed element are shifted downwards by one position. Syntax: Sta 2 min read Stack remove(int) method in Java with Example The Java.util.Stack.remove(int index) method is used to remove an element from a Stack from a specific position or index. Syntax: Stack.remove(int index) Parameters: This method accepts a mandatory parameter index is of integer data type and specifies the position of the element to be removed from t 2 min read Stack removeAllElements() method in Java with Example The Java.util.Stack.removeAllElements() method is used to removes all components from this Stack and sets its size to zero. Syntax: Stack.removeAllElements() Parameters: The method does not take any parameter Return Value: The function does not returns any value. Below programs illustrate the Java.u 2 min read Stack remove(Object) method in Java with Example The Java.util.Stack.remove(Object o) method is used to remove any particular element from the Stack. Syntax: Stack.remove(Object o) Parameters: This method accepts a mandatory parameter o is of the object type of Stack and specifies the element to be removed from the Stack. Return Value: Returns Tru 2 min read Stack addAll(int, Collection) method in Java with Example The addAll(int, Collection) method of Stack Class is used to append all of the elements from the collection passed as a parameter to this function at a specific index or position of a Stack. Syntax: boolean addAll(int index, Collection C) Parameters: This function accepts two parameters as shown in 2 min read Stack listIterator() method in Java with Example The listIterator() method of Java.util.Stack class is used to return a list iterator over the elements in this stack (in proper sequence). The returned list iterator is fail-fast.
