Create a simple class on different programming languages.

TypeScript

class MyClass {
  private message: string = '';

  public setMessage(message: string) {
    this.message = message;
  }

  public getMessage() {
    return this.message;
  }
}

const myClass = new MyClass();
myClass.setMessage("My message");

console.log(myClass.getMessage());

Go

package main

import "fmt"

type MyClass struct {
    message string
}

func (c *MyClass) setMessage(message string) {
    c.message = message
}

func (c *MyClass) getMessage() string {
    return c.message
}

func main() {
    myClass := MyClass{}
    myClass.setMessage("My message")
    fmt.Println(myClass.getMessage())
}

Python

class MyClass:
    def __init__(self):
        self.message = ''

    def set_message(self, message):
        self.message = message

    def get_message(self):
        return self.message

my_class = MyClass()
my_class.set_message("My message")

print(my_class.get_message())

PHP

class MyClass {
    private $message = '';

    public function setMessage($message) {
        $this->message = $message;
    }

    public function getMessage() {
        return $this->message;
    }
}

$my_class = new MyClass();
$my_class->setMessage("My message");

echo $my_class->getMessage();
