Java Pancake Recipe: A Deep Dive into Efficient and Elegant Code291

The term "Java Pancake" might seem unusual, but it perfectly encapsulates the essence of this article: taking a seemingly simple concept (a pancake recipe) and implementing it in Java in a robust, efficient, and elegant way. We won't just slap together a quick, messy program; instead, we'll explore various approaches, focusing on best practices and design patterns. This will illustrate how even straightforward tasks benefit from well-structured code.

Our "pancake recipe" will involve creating a class to represent a pancake. This class will hold information about the pancake, such as its diameter, ingredients, and cooking time. We’ll then build functions to create pancakes with different variations and calculate the total cooking time for a batch.

Let's start with a basic `Pancake` class:```java
public class Pancake {
private double diameter;
private String[] ingredients;
private int cookingTime; // in seconds
public Pancake(double diameter, String[] ingredients, int cookingTime) {
= diameter;
= ingredients;
= cookingTime;
}
public double getDiameter() {
return diameter;
}
public String[] getIngredients() {
return ingredients;
}
public int getCookingTime() {
return cookingTime;
}
@Override
public String toString() {
return "Pancake{" +
"diameter=" + diameter +
", ingredients=" + (ingredients) +
", cookingTime=" + cookingTime +
'}';
}
}
```

This simple class encapsulates the key attributes of a pancake. Notice the use of private fields and public getters – a fundamental aspect of encapsulation. The `toString()` method provides a convenient way to display the pancake's details.

Now, let's create a `PancakeMaker` class to handle the creation of pancakes:```java
import ;
import ;
public class PancakeMaker {
public static List makePancakes(int numPancakes, double diameter, String[] baseIngredients) {
List pancakes = new ArrayList();
for (int i = 0; i < numPancakes; i++) {
(new Pancake(diameter, baseIngredients, 60)); // Assumes 60 seconds cooking time
}
return pancakes;
}
public static int getTotalCookingTime(List pancakes) {
int totalTime = 0;
for (Pancake pancake : pancakes) {
totalTime += ();
}
return totalTime;
}
}
```

The `makePancakes` method efficiently creates a list of pancakes with specified parameters. The `getTotalCookingTime` method calculates the total cooking time for a batch. This demonstrates the use of collections (ArrayList) and iterative processing, common practices in Java development.

Let's add some error handling:```java
import ;
import ;
public class PancakeMaker {
// ... previous methods ...
public static List makePancakes(int numPancakes, double diameter, String[] baseIngredients) {
if (numPancakes
