class Liquid {

    private int mlVolume;
    private float temperature; // in Celsius

    public Liquid() {
        mlVolume = 300;
        temperature = (float) (Math.random() * 100.0);
    }

    public float getTemperature() {
        return temperature;
    }
    // Has several other methods, not shown...
}


class Coffee extends Liquid {

    private static final float BOILING_POINT = 50.0f; // Celsius
    private boolean swirling;
    private boolean clockwise;

    public Coffee(boolean swirling, boolean clockwise) {
        if (getTemperature() >= BOILING_POINT) {
            // Leave swirling at default value: false
            [b]return;[/b]
        }
        this.swirling = swirling;
        if (swirling) {
            this.clockwise = clockwise;
        } // else, leave clockwise at default value: false
    }
    void show()

    	System.out.println("BOILING_POINT "+BOILING_POINT);
    	System.out.println("temperature "+getTemperature());
    	System.out.println("swirling "+swirling);
    	System.out.println("clockwise "+clockwise);
    }
    // Has several methods, not shown,
    // but doesn't override getTemperature()...
    public static void main(String args[])

}

Hello
in above code, what does return do?
when getTemperature() >= BOILING_POINT, swirling becomes false, why?

It returns - exits the constructor method.

when getTemperature() >= BOILING_POINT, swirling becomes false, why?

swirling is false by default, it doesn't become false.
