Syntax:
Java
Java
Stack.removeAllElements()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:
Example 2:
Stack: [Welcome, To, Geeks, 4, Geeks] The final Stack: []
// 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: []
