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); 
    } 
}

输出：

Stack: [Welcome, To, Geeks, 4, Geeks]
The final Stack: []

示例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); 
    } 
}

输出：

Stack: [10, 15, 30, 20, 5]
