“ getName() “ function is used to get the name of a class which is instantiated here by an object named “C1”. This example shows that we can extract the information of primitive data types (which ultimately is the class in JAVA, and that is the reason JAVA is called a pure object-oriented language”. Boolean is a primitive data type like string, int, or char. This class is enabled with the help of the library declared above “”. The class “Class is the identifier reflection class in jAVA. This has a package that contains all the classes named “test.” The test package has a class “test declared.” This class also contains the main method from which the execution of the program will start. ("This is another instance of class is used to derive class name : "+c2.getName()) Įxplanation: Please check the example provided above. ("Here, the class name is: "+c1.getName())
Examples of Reflection in JAVAĭifferent examples are mentioned below: Example #1 This can be well understood with the help of examples provided in the below section. Reflection API is used in JAVA programs, IDEs (Integrated development environment) like the eclipse, Netbeans. These methods are defined in reflection API but return the class’s information, including methods, constructors, and more. The information about class can be extracted using getClass() method, Constructors using getConstructors() method and methods using getMethods() method. The reflection class uses different methods defined in the package to extract the class information. public boolean is primitive( parameter ): This function checks if the given parameter is primitive or not and returns a boolean value.public Class getSuperclass( parameter ): This function returns the superclass of the base class.In addition, it has a security exception and catches associated to make the program work break-free. public Method getDeclaredMethods( parameter ) throws SecurityException: This function checks the methods in the class and returns the number of methods used in a particular class.In addition, it has a security exception and catches associated with making the program work break-free. public Constructor getDeclaredConstructors( parameter ) throws SecurityException: This function checks the constructors in the class and returns the number of constructors used in a particular class.public boolean isArray( parameter ): This function checks if the variable is an array or not and returns a boolean (true or false) value.public boolean isInterface( parameter ): This function checks if the class is an interface or not and returns a boolean (true or false) value.public String getName( parameter ): This function returns the class name.

We will append your code with the Student class before running it.Start Your Free Software Development Course You have to fill in the incompleted lines so that it prints all the methods of another class called Student in alphabetical order.
In this problem, you will be given a class Solution in the editor. For example, we can retrieve the list of public fields of a class using getDeclaredMethods(). JAVA reflection is a very powerful tool to inspect the attributes of a class in runtime. Link for the Problem – Java Reflection Attributes – Hacker Rank Solution Java Reflection Attributes – Hacker Rank Solution Objective Java applications are compiled to byte code that can run on any Java Virtual Machine. A general-purpose programming language made for developers to write once run anywhere that is compiled Java code can run on all platforms that support Java. Java is a class-based, object-oriented programming language and is designed to have as few implementation dependencies as possible. It helps to create reusable code and modular programs. Java makes writing, compiling, and debugging programming easy. JAVA was developed by James Gosling at Sun Microsystems Inc in the year 1991, later acquired by Oracle Corporation.
