Vector setElementAt() method in Java with Example
The setElementAt() method of Java Vector is used to set the component at the specified index of this vector to be the specified object. The previous component at that position is discarded. The index must be a value greater than or equal to 0 and less than the current size of the vector.
public void setElementAt(E element, int index)
Parameters: This function accepts two parameters as shown in the above syntax and described below.
- element: It is the new element by which the existing element will be replaced and is of the same object type as the vector.
- index: This is of integer type and refers to the position of the element that is to be replaced from the vector.
Return Value: This method do not return anything.
Exception: This method throws ArrayIndexOutOfBoundsException if the index is out of range (index = size())
Below program illustrate the Java.util.Vector.setElementAt() method:
Vector:[Geeks, for, Geeks, 10, 20] Geeks replaced with GFG The new Vector is:[Geeks, for, GFG, 10, 20]
Example 2: To demonstrate ArrayIndexOutOfBoundsException
Vector:[Geeks, for, Geeks, 10, 20] Trying to replace 10th element with GFG java.lang.ArrayIndexOutOfBoundsException: 10 >= 5
