java.lang.NoSuchMethodException

I'm getting an error when getting a constructor with 4 integers. The method itself essentially exists but Java throws an exception 
ColorType type;
try {
    Constructor<ColorType> c =ColorType.class.getConstructor(Integer.TYPE, Integer.TYPE, Integer.TYPE, Integer.TYPE);
    c.setAccessible(true);
    type = c.newInstance(255, 0, 0, 0);
} catch (NoSuchMethodException | InvocationTargetException | InstantiationException | IllegalAccessException e) {
    throw new RuntimeException(e);
}
        
settings.background_color = type;
ColorType type;
try {
    Constructor<ColorType> c =ColorType.class.getConstructor(Integer.TYPE, Integer.TYPE, Integer.TYPE, Integer.TYPE);
    c.setAccessible(true);
    type = c.newInstance(255, 0, 0, 0);
} catch (NoSuchMethodException | InvocationTargetException | InstantiationException | IllegalAccessException e) {
    throw new RuntimeException(e);
}
        
settings.background_color = type;

If it is an inner class, it actually has 5 argument the first argument is an object of the outer class Alternatively, just make the inner class static static class ColorType

And I think you might need to use int.class, Integer is not the same as int

Integer.TYPE is int.class
