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 !!!
