Vector Class setElementAt() method

  • setElementAt() method is available in java.util package.
  • setElementAt() method is used to set the given element (ele) at the given indices in this Vector.
  • setElementAt() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • setElementAt() method may throw an exception at the time of setting an element.
    ArrayIndexOutOfBoundsException: This exception may throw when the given first parameter is not in a range.

Syntax:

    public void setElementAt(Element ele, int indices);

Parameter(s):

  • Element ele – represents the element to be set at the given indices.
  • int indices – represents the indices of the given element to be set.

Return value:

The return type of the method is void, it returns nothing.

Example:

// Java program to demonstrate the example 
// of void setElementAt(Element ele, int indices) method 
// of Vector 

import java.util.*;

public class SetElementAtOfVector {
 public static void main(String[] args) {
  // Instantiates a Vector object  with
  // initial capacity of "10"
  Vector < String > v = new Vector < String > (10);

  // By using add() method is to add the
  // elements in this v
  v.add("C");
  v.add("C++");
  v.add("JAVA");

  // Display Vector
  System.out.println("v: " + v);

  // By using setElementAt() method is to
  // set the element at the given indices
  v.setElementAt("SFDC", 2);

  // Display updated vector
  System.out.println("v.setElementAt(SFDC, 2): " + v);
 }
}

Output

v: [C, C++, JAVA]
v.setElementAt(SFDC, 2): [C, C++, SFDC]
