Methods-and-Constructors
Methods and constructors are fundamental concepts in object-oriented programming, particularly in languages like Java. Methods are blocks of code designed to perform specific tasks, allowing for code reusability and organization. They can accept parameters and return values, enabling dynamic interactions within a program. Constructors, on the other hand, are special methods used to initialize new objects of a class. They share the class name and do not have a return type. Constructors can also take parameters to set initial values for object attributes. Understanding both methods and constructors is essential for effective programming and object management.
Constructors
Constructors are special methods named after the class and without a return type, and are used to construct objects. Constructors, like methods, can take input parameters. Constructors are used to ini...
