Strongtalk

A blast from the past!

Strongtalk is a now-obsolete, object-oriented programming language developed by Sun Microsystems (now Oracle Corporation) in the 1980s. It was designed to be a more efficient and safer alternative to C++.

Here’s an example of how to write “Hello World!” in Strongtalk:

#include <stdio.h>

class HelloWorld {
    public:
        void main() {
            printf("Hello, World!\n");
        }
};

main: HelloWorld();

Let me explain what’s going on:

• The first line includes the stdio.h header file, which provides functions for input/output operations.
• The HelloWorld class defines a single method called main, which is where the program starts execution. In this case, it simply prints “Hello, World!” to the console using printf.
• The main: label specifies the entry point of the program, which is an instance of the HelloWorld class.

To compile and run this code, you would need a Strongtalk compiler, such as the original Sun Microsystems Strongtalk compiler or a third-party implementation like the open-source Strongtalk project. Unfortunately, these compilers are no longer widely available or supported, so it’s unlikely that you can actually run this code today.
