This method gets the value of a static or instance field of type double or of another primitive type convertible to type double via a widening conversion This method returns the Class object representing the class or interface that declares the field represented by this Field object This method returns annotations that are directly present on this element This method gets the value of a static or instance field of type char or of another primitive type convertible to type char via a widening conversion This method gets the value of a static or instance byte field This method gets the value of a static or instance boolean field This method returns annotations that are associated with this element This method returns this element’s annotation for the specified type if such an annotation is present, else null. This method returns an AnnotatedType object that represents the use of a type to specify the declared type of the field represented by this Field This method compares this field against the specified object. They return an array of Field objects that provide information about the object. Once this is obtained, getFields() is used to analyze the class object. The program begins with forName() method of Class to get a class object for. The following application illustrates a simple use of java reflection. AccessibleObject, Array, Constructor, Executable, Field, Method, Modifier, Parameter, Proxy, ReflectPermission. There are also ten classes in this package i.e. Of special interest is Member which defines methods that allow getting information about a field, constructor or method of a class. The package includes several interfaces. Reflection mechanisms allow one to bypass it to some degree, and introduce some more dynamic features, like, say, retrieval of the value of the field by name. Java, like many other languages, is statically typed. Field serves the same purpose as the whole reflection mechanism, analyze a software component and describe its capabilities dynamically, at run time rather than at compile time. This is provided by the package and elements in Class. The ability of the software to analyze itself is known as Reflection. ISRO CS Syllabus for Scientist/Engineer Exam.
