Vector removeAllElements() method in Java with Example
The Java.util.Vector.removeAllElements() method is used to removes all components from this Vector and sets its size to zero. Syntax:
Vector.removeAllElements()
Parameters: The method does not take any parameter
Return Value: The function does not returns any value.
Below programs illustrate the Java.util.Vector.removeAllElements() method.
Example 1:
Java
// Java code to illustrate removeAllElements()import java.util.*;public class GFG { public static void main(String args[]) { // Creating an empty Vector Vector<String> vector = new Vector<String>(); // Use add() method to add elements into the Vector vector.add("Welcome"); vector.add("To"); vector.add("Geeks"); vector.add("4"); vector.add("Geeks"); // Displaying the Vector System.out.println("Vector: " + vector); // removeAllElementsing the Vector // using removeAllElements() method vector.removeAllElements(); // Displaying the final Vector after removeAllElement System.out.println("The final Vector: " + vector); }} |
Output:
Vector: [Welcome, To, Geeks, 4, Geeks] The final Vector: []
Example 2:
Java
// Java code to illustrate removeAllElements()import java.util.*;public class GFG { public static void main(String args[]) { // Creating an empty Vector Vector<Integer> vector = new Vector<Integer>(); // Use add() method to add elements into the Queue vector.add(10); vector.add(15); vector.add(30); vector.add(20); vector.add(5); // Displaying the Vector System.out.println("Vector: " + vector); // removeAllElementsing the Vector // using removeAllElements() method vector.removeAllElements(); // Displaying the final Vector after removeAllElement System.out.println("The final Vector: " + vector); }} |
Output:
Vector: [10, 15, 30, 20, 5] The final Vector: []
Time complexity: O(n). // n is the size of the vector.
Auxiliary space: O(1)
