Introduction
The Facade design pattern is a structural pattern that provides a simplified interface to a complex subsystem, making it easier to use. This pattern is useful for reducing the complexity of client interactions with subsystems by offering a higher-level interface. In this article, we’ll explore how the Facade pattern can be used to simplify the interaction with a computer system, by providing a single interface to start and shut down the computer. Let’s see how this pattern can be practically applied with a detailed example.
Implementation
- Define Subsystem Classes: Create classes that represent the complex subsystems. In our example, these are
CPU,Memory, andHardDrive, each with their own methods.
class CPU {
void freeze() {
print("CPU: Freezing...");
}
void jump(String position) {
print("CPU: Jumping to $position");
}
void execute() {
print("CPU: Executing...");
}
}
class Memory {
void load() {
print("Memory: Loading data...");
}
}
class HardDrive {
void read(String sector, int size) {…
