> 1. I’m amazed that you call Java ugly and verbose but recommend C++. Apart from files not needing to be classes in C++, they feel similarly verbose to me with C++ slightly winning on ugliness.
I've always found java much much more verbose. here's e.g. hello world in javafx:
package helloworld;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class HelloWorld extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler() {
@Override
public void handle(ActionEvent event) {
System.out.println("Hello World!");
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
}
here's a Qt version:
#include
int main(int argc, char** argv) {
QApplication app{argc, argv};
QPushButton button{"Say 'Hello World'"};
button.setWindowTitle("Hi");
QObject::connect(&button, &QPushButton::clicked, [] {
puts("Hello world !");
});
button.setMinimumSize({300, 250});
button.show();
return app.exec();
}
notice for instance creating an object just with {} ; just that saves me I don't know how many hundreds of keystrokes. Also no need to ever `new` anything, just name the types directly. No need to repeat types à la
StackPane root = new StackPane();
C++ would just be
StackPane root;
or maybe
auto root = StackPane{foo, bar};
observer pattern can be much less braindead thanks to the early existence of templates, and let's not even talk about

like, come on...
same for Optional which gets some unrelated custom OptionalInt because there was no value type and adds boilerplate for nothing.
