What are method local inner classes in Java?

In Java, we can write a class within a method and this will be a local type. Like local variables, the scope of the inner class is restricted to the method.

A method-local inner class can be instantiated only within the method where the inner class is defined. The following program shows how to use a method-local inner class.

Example

Live Demo

public class OuterClass {    public void display(){       int num = 23;       class Inner{          public void print() {             System.out.println("This is method inner class "+num);          }       }       Inner obj = new Inner();       obj.print();    }    public static void main(String args[]){       OuterClass outer = new OuterClass();       outer.display();    } }

Output

This is method inner class 23
