Unused variable included in the extracted method after using "Extract to method" code action

[gayalkuruppu]

Refer the following scenario.

In here, the unused variable a is there in the extracted() method, which can be removed with the original extract to method code action.

Code to reproduce:

public class Extract {

    public static void main(String[] args) {
        int a;
        int b = 1;
        a = 1;
        b = a + b;
    }
}

Expected output:

public class Extract {

    public static void main(String[] args) {
        int a;
        int b = extracted();
        a = 1;
        b = a + b;
    }

    private static int extracted() {
        int b = 1;
        return b;
    }
}
