FAQ from Java Interview Assistant?
Java provides four access modifiers: private, default, protected, and public. Private variables, methods, and constructors can only be accessed within the same class. Default variables, methods, and constructors can be accessed within the same package. Protected variables, methods, and constructors can be accessed within the same package or its subclasses. Public variables, methods, and constructors can be accessed from anywhere.
A constructor is a special method declared with the same name as the class. It is used to initialize the object's variables and allocate memory for the object. The constructor is called when an object of the class is created. Java provides a default constructor if a class doesn't have any constructor. A constructor can have any number of parameters and can be overloaded for different parameter types.
ArrayList and LinkedList are two different implementations of the List interface in Java. ArrayList is implemented as a resizable array, whereas LinkedList is implemented as a doubly linked list. ArrayList provides fast random access and is efficient for adding or removing elements at the end of the list. LinkedList provides fast adding or removing elements from any position in the list, but slower random access. Choose the implementation that best suits your needs based on the operations that you need to perform.
