What is the Flyweight pattern in C++ and Java?

Can you explain the Flyweight pattern in C++ and Java?

The Flyweight pattern is a structural design pattern that minimizes memory usage by sharing common parts of state between multiple objects.

How does it work in practice?

In practice, the Flyweight pattern involves creating a factory that manages the shared objects and provides them to clients as needed.

Can you give me a code example in Java?

Sure! Here's a simple example:

class Flyweight {
    private String intrinsicState;
    public Flyweight(String state) {
        this.intrinsicState = state;
    }
    public void operation(String extrinsicState) {
        System.out.println("Intrinsic: " + intrinsicState + ", Extrinsic: " + extrinsicState);
    }
}

What about C++? Is it similar?

Yes, it's quite similar! In C++, you would create a Flyweight class and a factory to manage the instances, just like in Java.
