Question

This is my third (and hopefully final) question today.

Is it possible to declare the value of a variable to the variable of a class, where the name of the class is a string?

Example

int newalpha;
String color_name = "yellow";
Color red = new Color();
Color yellow = new Color();
Color blue = new Color();
newalpha = color_name.alpha

In this example, “.alpha” is a variable contained inside of the Color class. The part I’m wanting to simulate is the “newalpha = color_name.alpha”, because obviously “color_name” is a String, not a color. Is this possible?

Thanks

TL;DR answer: no.

Reality: yes, sort of, via reflection, and ew.

Depending on your use case, there may be a way to achieve what you want, like by storing the colors in a hash map with the color names as the keys, so you’d just say colors.get(colorName).alpha.

Map<String, Color> colors = new HashMap<String, Color>() {{
    put("red", new Color());
    put("yellow", new Color());
    put("blue", new Color());
}};
String colorName = "yellow";
int newalpha = colors.get(colorName).alpha;
