Vector removeElement() method in Java with Example
The java.util.Vector.removeElement() method is used to remove first occurrence of particular object. If object is not found then it returns false else it returns true. If a particular object is present inside vector and removeElement() method call on that vector element then this method reduces vector size by 1.
public boolean removeElement(Object obj)
Parameters: This function accepts object as parameter which is to be removed.
Return Type: On Successful of deletion this function returns True otherwise this function returns False.
Exceptions: This method does not raise any exception.
Below programs illustrates the Vector.removeElement() function.
Before deleting Vector: [1, 2, 3, 4, 5, 6] Size: 6 After deleting Element '3' has been removed Vector: [1, 2, 4, 5, 6] Size: 5
Before deleting Vector: [1, 2, 3, 4, 5, 6] Size: 6 After deleting Element '15' is not present in Vector Vector: [1, 2, 3, 4, 5, 6] Size: 6
Time complexity: O(n). // n is the size of the vector.
Space complexity: O(1).
