Is there any code I could write that is more effective and clean rather than a bunch of else if statements?

I'm more of an intermediate android dev and I want to learn how to write more clean and effective code, and I've come to this problem on my app that requires to check a bunch of statements like if a variable is less than something or more for each individual rating.

        //For Dividend Stocks
        if(currentDiv != 0 && fiveYearDiv != 0){

            double dividendDiff = currentDiv - fiveYearDiv;

            if (peRatio <= 20 && peRatio > 0  && dividendDiff >= 0.01 && payoutRatio <= 0.65) {
                int stockRatingDividend = 5;
                addItems(stockRatingDividend);
            } else if (peRatio > 20 && peRatio <= 25 && dividendDiff >= 0.005 && payoutRatio <= 0.75) {
                int stockRatingDividend = 4;
                addItems(stockRatingDividend);
            } else if (peRatio > 25 && peRatio <= 30 && dividendDiff >= 0.001 && payoutRatio <= 0.85) {
                int stockRatingDividend = 3;
                addItems(stockRatingDividend);
            } else if (peRatio > 30 && peRatio <= 35 && payoutRatio <= 0.95) {
                int stockRatingDividend = 3;
                addItems(stockRatingDividend);
            }
            else if( peRatio > 35 &&  peRatio <= 40 && currentDiv > fiveYearDiv && payoutRatio >= 100) {
                int stockRatingDividend = 2;
                addItems(stockRatingDividend);
            } else if( peRatio > 40 || peRatio < 0 && fiveYearDiv > currentDiv  && payoutRatio >= 100) {
                int stockRatingDividend = 1;
                addItems(stockRatingDividend);
            }
            else {
                int stockRatingDividend = 0;
                addItems(stockRatingDividend);
           }

As you can see by the code above it's very messy and cluttered and doesn't even work correctly, because there are too many conditions it has to check and it usually doesn't fit into any else if statement and just returns 0

I know it might be a lot but can someone at least guide me to a post or something on how I could write more effective and clean code rather than a cluttered mess of else if statements for this block of code?
