how to turn this piece of code into one line of code?

I’m a beginner to Java and was wondering if there is a way to rewrite the below code in 1 one line while keeping its functionality the same?

private boolean colour_chosen(Colour Colour, boolean red, boolean blue, boolean yellow) {
        if (Colour instanceof redColour) {
            if (red) return true;
            else return false;
        } else if (Colour instanceof blueColour) {
            if (blue) return true;
            else return false;
        } else if (Colour instanceof yellowColour) {
            if (yellow) return true;
            else return false;
        } else {
            return false;
        }
    }

>Solution :

You can replace the if blocks by logical expressions. That way, the entire method body reduces to:

return (Colour instanceof redColour && red) || (Colour instanceof blueColour && blue) || (Colour instanceof yellowColour && yellow);

However, it’s questionable how readable this is; having a single expression is fine, but I would still split it across lines.

The parentheses in the code above are unnecessary because && has precedence over || but many people prefer them.

In general, code of the form if (condition) return true; else return false; can — and should! — always be replaced by return condition;.
