package com; public class Student { private String name; private int age; public Student(String name, int age) { super(); this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }ReflectionDemo1.java
public class ReflectionDemo1 { public static void main(String[] args) { try { /* * forName() method is used to load the class dynamically * * Returns:the Class object for the class with the * specified name. * * forName() method should be used if you know the fully * qualified name of class.This cannot be used for * primitive types. r */ Class<?> classObj = Class.forName("com.Student"); System.out.println(classObj.getName()); System.out.println(classObj.getSimpleName()); } catch (ClassNotFoundException e) { e.printStackTrace(); } } }Output
com.Student
Student
ReflectionDemo2.javaimport com.Student; public class ReflectionDemo2 { public static void main(String[] args) { Student student = new Student("Peter", 25); /* * Returns:The Class object that represents the runtime class of this * object. */ Class<? extends Student> classObj = student.getClass(); System.out.println(classObj.getName()); } }Output
com.Student
ReflectionDemo3.javaimport com.Student; public class ReflectionDemo3 { public static void main(String[] args) { /* * If a type is available but there is no instance then it is possible * to obtain a Class by appending ".class" to the name of the type.It * can be used for primitive data type also. */ Class<Student> studentClassObj = Student.class; System.out.println(studentClassObj.getName()); Class<Integer> intClassObj = int.class; System.out.println(intClassObj.getName()); } }Output
com.Student
int
