Parameters: The method does not take any parameter

Return Value: The function does not returns any value.

Below programs illustrate the Java.util.Stack.removeAllElements() method.



Example 1:




// Java code to illustrate removeAllElements()
import java.util.*;
  
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 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);
  
        // removeAllElementsing the Stack
        // using removeAllElements() method
        stack.removeAllElements();
  
        // Displaying the final Stack after removeAllElementsing
        System.out.println("The final Stack: " + stack);
    }
}
Output:
Stack: [Welcome, To, Geeks, 4, Geeks]
The final Stack: []

Example 2:




// Java code to illustrate removeAllElements()
import java.util.*;
  
public class GFG {
    public static void main(String args[])
    {
        // Creating an empty Stack
        Stack<Integer> stack = new Stack<Integer>();
  
        // Use add() method to add elements into the Queue
        stack.add(10);
        stack.add(15);
        stack.add(30);
        stack.add(20);
        stack.add(5);
  
        // Displaying the Stack
        System.out.println("Stack: " + stack);
  
        // removeAllElementsing the Stack
        // using removeAllElements() method
        stack.removeAllElements();
  
        // Displaying the final Stack after removeAllElementsing
        System.out.println("The final Stack: " + stack);
    }
}
Output:
Stack: [10, 15, 30, 20, 5]
The final Stack: []
