java - How do I compare any date with the current date, without taking the year into account

I want to compare the date with the current date, without taking the year into account, and I want to change the text for each day

Here is my code

TextView textView = (TextView)findViewById(R.id.textView);

        String valid_until = "7/3";
        String valid_until1 = "8/3";
        String valid_until2 = "9/3";
        String valid_until3 = "10/3";

        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM");
        Date strDate = null;
        Date strDate1 = null;
        Date strDate2 = null;
        Date strDate3 = null;


        try {
            strDate = sdf.parse(valid_until);
            strDate1 = sdf.parse(valid_until1);
            strDate2 = sdf.parse(valid_until2);
            strDate3 = sdf.parse(valid_until3);


        } catch (ParseException e) {
            e.printStackTrace();
        }
        if (new Date() == (strDate)) {
            textView.setText("7 m");
        }
        if (new Date() == (strDate1)) {
            textView.setText("8 m");
        }
        if (new Date() == (strDate2)) {
            textView.setText("9 m");
        }
        if (new Date() == (strDate3)) {
            textView.setText("10 m");
        }

One option, you could use a Calendar object. Set the date on each, and then simply compare the "DAY_OF_YEAR" value.
