Here, we will create two objects of Vector collection. Then we will check a vector is empty or not using the isEmpty() method. After that, we will print the appropriate message on the console screen.
The Vector is an immutable data structure. We can access vector elements randomly. It extends an abstract class AbstractSeq and IndexedSeq trait. We use the Vector collection to store a large number of elements.
Program/Source Code:
The source code to check a vector is empty or not is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.
Output:
Explanation:
Here, we used an object-oriented approach to create the program. And, we imported Collection classes using the below statement,
And, we also created a singleton object Sample and defined the main() function. The main() function is the entry point for the program.
In the main() function, we created two vectors vector1 and vector2 using Vector collection. Then we checked vector is empty or not using the isEmpty() method and print the appropriate message on the console screen.
