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.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: []
