remove(int index)
The java.util.vector.remove(int index) method is used to remove an element from a Vector from a specific position or index. Syntax:Vector.remove(int index)
Parameters: This method accepts a mandatory parameter index is of integer data type and specifies the position of the element to be removed from the Vector. Return Value: This method returns the element that has just been removed from the vector. Below program illustrate the Java.util.Vector.remove(int index) method:Java // Java code to illustrate remove() when position of // element is passed as parameter import java.util.*; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<String> vec_tor = new Vector<String>(); // Use add() method to add elements in the Vector vec_tor.add("Geeks"); vec_tor.add("for"); vec_tor.add("Geeks"); vec_tor.add("10"); vec_tor.add("20"); // Output the Vector System.out.println("Vector: " + vec_tor); // Remove the element using remove() String rem_ele = vec_tor.remove(4); // Print the removed element System.out.println("Removed element: " + rem_ele); // Print the final Vector System.out.println("Final Vector: " + vec_tor); } }
Output:Vector: [Geeks, for, Geeks, 10, 20] Removed element: 20 Final Vector: [Geeks, for, Geeks, 10]
remove(Object o)
The java.util.vector.remove(Object o) method is used to remove any particular element from the Vector. Syntax:Vector.remove(Object o)
Parameters: This method accepts a mandatory parameter o is of the object type of Vector and specifies the element to be removed from the Vector. Return Value: Returns True if the specified element is found and removed from the Vector, else False. Below program illustrate the Java.util.Vector.remove(Object O) method:Java // Java code to illustrate remove() method import java.util.*; public class VectorDemo { public static void main(String args[]) { // Creating an empty Vector Vector<String> vec_tor = new Vector<String>(); // Use add() method to add elements in the Vector vec_tor.add("Geeks"); vec_tor.add("for"); vec_tor.add("Geeks"); vec_tor.add("10"); vec_tor.add("20"); // Output the Vector System.out.println("Vector: " + vec_tor); // Remove the head using remove() Boolean rem_ele; rem_ele = vec_tor.remove("Geeks"); // Print the removed element if (rem_ele) System.out.println("Geeks" + " found and removed."); else System.out.println("Geeks" + " not found or removed."); rem_ele = vec_tor.remove("500"); // Print the removed element if (rem_ele) System.out.println("500" + " found and removed."); else System.out.println("500" + " not found or removed."); // Print the final Vector System.out.println("Final Vector: " + vec_tor); } }
Output:Vector: [Geeks, for, Geeks, 10, 20] Geeks found and removed. 500 not found or removed. Final Vector: [for, Geeks, 10, 20]
