Often a setter is accompanied by a getter, which returns the value of the private member variable. They are also known collectively as accessors . The mutator method is most often used in object-oriented programming , in keeping with the principle of encapsulation .
A JavaBean is a POJO that is serializable, has a no-argument constructor, and allows access to properties using getter and setter methods that follow a simple naming convention. Because of this convention, simple declarative references can be made to the properties of arbitrary JavaBeans.
The Java platform has various ad-hoc annotation mechanisms—for example, the transient modifier, or the @Deprecated javadoc tag. The Java Specification Request JSR-175 introduced the general-purpose annotation (also known as metadata) facility to the Java Community Process in 2002; it gained approval in September 2004.
Java has a set of predefined annotation types, but it is allowed to define new ones. An annotation type declaration is a special type of an interface declaration. They are declared in the same way as the interfaces, except the interface keyword is preceded by the @ sign.
A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.
A property is a subset of a Bean's state. The values assigned to the properties determine the behaviour and appearance of that component. They are set through a setter method and can be obtained by a getter method. Customization A customizer can provide a step-by-step guide that the process must follow to use the component in a specific context ...
In computer programming, field encapsulation involves providing methods that can be used to read from or write to the field rather than accessing the field directly. . Sometimes these accessor methods are called getX and setX (where X is the field's name), which are also known as mutato
But, unlike C++, Java doesn't create a default copy constructor if you don't write your own. Copy constructors define the actions performed by the compiler when copying class objects. A Copy constructor has one formal parameter that is the type of the class (the parameter may be a reference to an object).
