Minimal example of instantiating and using objects of a static inner class

Enclosing.java

import lombok.Data;

public class Enclosing {
    @Data
    public static class Inner {
        private String value;
    }

    public static void main(String[] args) {
        Inner inner1 = new Inner();
        inner1.setValue("foo");

        Inner inner2 = new Inner();
        inner2.setValue("bar");

        System.out.println(inner1.getValue()); // prints "foo"
        System.out.println(inner2.getValue()); // prints "bar"
    }
}
