How to resolve Variable in lambda expression should be final or effectively final in forEach Java 8

I want to limit the number of values in an ArrayList in the below code

}




I decided to use this way,

int i = 0;
i++;
});
but this gives me the error "Variable used in lambda expression should be final or effectively final"

Because this variable I is incrementing inside lambda expression it is not final so this gives the above error.

So I fixed this by using the AtomicInteger in the below way,

AtomicInteger atomicInteger=new AtomicInteger();
}
}

}
);
This solves the issue and I can see the list correctly with six elements
