By default this function initializes a vector of specified length with all empty string as values, so to create empty vector just use character() function with out any arguments. It creates a vector of type character .
How do you add elements at the end of a vector?
Elements can be added at the end of a Vector using the java. util. Vector. add() method.
How do you add elements to a vector in a loop?
