package BusinessRules

#list any import classes here.
import com.drools.test.StockOffer;

#declare any global variables here

function void printStock( StockOffer stock ) {
    #function content (can have multiple functions)
    System.out.println("Name: "
        + stock.getStockName()
        + " Price: " + stock.getStockPrice()
        + " BUY: " + stock.getRecommendPurchase());
}

rule "Stock Price Low Enough"
    when
        #conditions
        offer : StockOffer(recommendPurchase == null, stockPrice < 100)
    then
        #actions
        offer.setRecommendPurchase( StockOffer.YES );
        printStock( offer );
end

Results in:
