Example

/**
 *  Before replacing temporary variables with queries 
 * Created by luo on 2017/4/19.
 */
public class ReplaceTempWithQueryBefore {
    private double _quantity;
    private double _itemPrice;

    public double test() {
        double basePrice = _quantity * _itemPrice;
        if (basePrice > 1000) {
            return basePrice * 0.95;
        } else {
            return basePrice * 0.98;
        }
    }
}

/**
 *  After replacing temporary variables with queries 
 * Created by luo on 2017/4/19.
 */
public class ReplaceTempWithQueryAfter {
    private double _quantity;
    private double _itemPrice;

    public double test() {
        if (basePrice() > 1000) {
            return basePrice() * 0.95;
        } else {
            return basePrice() * 0.98;
        }
    }

    private double basePrice() {
        return _quantity * _itemPrice;
    }
