Stack capacity() method in Java with Example

Last Updated : 24 Dec, 2018

The capacity() method of Stack Class is used to get the capacity of this Stack. That is the number of elements present in this stack container. Syntax:

public int capacity()

Parameters: This function accepts a parameter E obj which is the object to be added at the end of the Stack. Return Value: The method returns integer value which is the capacity of the Stack Below program illustrate the Java.util.Stack.capacity() method: Example 1:

Java

// Java code to illustrate boolean capacity()

import java.util.*;
import java.util.ArrayList;

public class GFG {
    public static void main(String args[])
    {
        // Creating an empty Stack
        Stack<String> stack = new Stack<String>();

        // Use add() method to add elements in the Stack
        stack.add("Geeks");
        stack.add("for");
        stack.add("Geeks");
        stack.add("10");
        stack.add("20");

        // Displaying the Stack
        System.out.println("The Stack is: " + stack);

        // checking capacity
        System.out.println("Capacity: "
                           + stack.capacity());
    }
}

Output:

The Stack is: [Geeks, for, Geeks, 10, 20]
Capacity: 10

Example 2:

Java

// Java code to illustrate
// boolean add(Object element)

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 in the Stack
        stack.add(10);
        stack.add(20);
        stack.add(30);
        stack.add(40);
        stack.add(50);

        // Displaying the Stack
        System.out.println("The Stack is: " + stack);

        // checking capacity
        System.out.println("Capacity: "
                           + stack.capacity());
    }
}

Output:

The Stack is: [10, 20, 30, 40, 50]
Capacity: 10
