How to instantiate a static inner class with reflection in Java?
A static inner class can be instantiated without the need for an instance of the outer class. In general, an Inner class is a part of nested class, called Non-static nested classes in Java. The types of inner classes are member inner class, anonymous inner class, and local inner class.
We can instantiate a static inner class with reflection using InnerClass.class.newInstance(). If we need an instance of the outer class to instantiate a non-static inner class, we can specify it before a new operator.
Example
import java.lang.reflect.*; public class InnerclassWithReflectionTest { public static void main(String args[]) { try { InnerClass inner = (InnerClass) InnerClass.class.newInstance(); inner.test(); } catch(Exception e) { e.printStackTrace(); } } // inner class static class InnerClass { public void test() { System.out.println("Welcome to TutorialsPoint !!!"); } } }
Output
Welcome to TutorialsPoint !!!
