Nested Interfaces in Java

Nested Interfaces in Java

Create a Java program to demonstrate the use of nested interfaces

The Outer interface contains a method outerMethod() and a nested interface Inner containing a method innerMethod().
The MyClass class implements the Inner interface and provides an implementation for the innerMethod() method.
In the Main class, we create an instance of MyClass and call the innerMethod(), which prints "Inner method implementation" to the console.

Source Code

interface Outer
{
	void outerMethod();
 
	interface Inner
	{
		void innerMethod();
	}
}
 
class MyClass implements Outer.Inner
{
	@Override
	public void innerMethod()
	{
		System.out.println("Inner method implementation");
	}
}
 
public class Main
{
	public static void main(String[] args)
	{
		MyClass myClass = new MyClass();
		myClass.innerMethod();
	}
}

Output

Inner method implementation
