How can I implement design patterns in C++ and Java?

You can implement design patterns in both languages by following their specific syntax and paradigms. Which pattern are you interested in?

I'm particularly interested in the Singleton pattern.

In C++, you can create a Singleton by making the constructor private and providing a static method to access the instance. In Java, you can use a private constructor and a static instance variable. Would you like code examples?

Yes, please provide examples for both languages.

Sure! For C++, it looks like this:

class Singleton {
private:
    Singleton() {}
public:
    static Singleton& getInstance() {
        static Singleton instance;
        return instance;
    }
};

And for Java:

public class Singleton {
    private static Singleton instance;
    private Singleton() {}
    public static Singleton getInstance() {
        if (instance == null) {
            instance = new Singleton();
        }
        return instance;
    }
}
