Java Interview Questions For Freshers

[Akshay-pjd]

Collection is an interface but collections is an utility class which is very common difference

[savronbeksirojiddinov]

the key difference is that an array has a fixed size, while an ArrayList can dynamically expand and shrink its size as elements are added or removed. Additionally, the additional functions and features provided by ArrayList make it more flexible and convenient to use compared to an array.

[savronbeksirojiddinov]

the main difference between a set and a map is that a set stores unique elements without any specific ordering, while a map stores key-value pairs with a specific ordering based on the keys.

[savronbeksirojiddinov]

Collection" is an interface that represents a group of objects, while "Collections" is a utility class that provides useful methods for working with Collection objects.

[savronbeksirojiddinov]

ArrayList is typically more efficient, especially in single-threaded applications. Vector, on the other hand, is useful in multi-threaded scenarios where thread-safety is needed.
