What are the difference between an array and a vector? Explain the advantage and disadvantage of both.
Both arrays and vectors are used to store collections of elements in Java. However, there are some differences between them: Dynamic vs. Static Size: Arrays have a fixed size that is set at the time of creation and cannot be changed. In contrast, Vectors can grow or shrink dynamically as elements are added or removed. Synchronization: Vectors are synchronized, which means that only one thread can access a vector at a time, while arrays are not synchronized. Performance: Arrays are generally faster than Vectors because they are not synchronized and do not need to dynamically resize. Type safety: Arrays can be created for any data type, including primitives, while Vectors can only hold objects. Flexibility: Vectors have some built-in methods for adding and removing elements, while Arrays have a fixed set of methods and require more manual manipulation. Advantages of Arrays: Fixed size provides better performance in some cases. Arrays are more memory efficient than Vectors. Arrays ca...
