Flipping the order of the if and else branches usually increases the clarity of such statements.

There is a fix that inverts the current if statement.

Example:

    void m(Object o1, Object o2) {
        if (o1 != o2) {
            System.out.println(1);
        }
        else {
            System.out.println(2);
        }
    }

After applying the quick-fix:

    void m(Object o1, Object o2) {
        if (o1 == o2) {
            System.out.println(2);
        } else {
            System.out.println(1);
        }
    }

Use the Ignore '!= null' comparisons option to ignore comparisons of the != null form.

Use the Ignore '!= 0' comparisons option to ignore comparisons of the != 0 form.
