Vector contains() Method in Java
The java.util.vector.contains() method is used to check whether a specific element is present in the Vector or not. So basically it is used to check if a vector contains any particular element or not. Syntax:
Parameters: This method takes a mandatory parameter element which is of the type of vector. This is the element that needs to be tested if it is present in the vector or not. Return Value: This method returns True if the element is present in the vector otherwise it returns False. Below programs illustrate the Java.util.Vector.contains() method: Program 1:
Vector: [Welcome, To, Geeks, 4, Geeks] Does the vector contains 'Geeks'? true Does the Vector contains '4'? true Does the Queue contains 'No'? false
Vector: [10, 15, 30, 20, 5] Does the vector contains 'Geeks'? false Does the Vector contains '4'? false Does the Vector contains 'No'? false
Time complexity: O(n), // n is the number of elements in the vector.
Auxiliary space: O(n)
