Sean O ́ :
I'm trying to add Hardware Components to a PCB which contains arrays of objects and I am not able to pass the object to the array. This is my first Java Project so total newbie here. Please Help!
public class PCB {
private Collection<HardwareComponent> hwComponents = new Vector<HardwareComponent>();
private Collection<CircuitPath> connections = new Vector<CircuitPath>();
public void placeComponent(<HardwareComponent> hw) {
hwComponents.add(hw);
}
And my Main
public class Configurator {
public static void main(String[] args) {
PCB pcb = new PCB();
HardwareComponent c1 = new Capacitor("cap1", 0.55f);
HardwareComponent c2 = new Capacitor("cap2", 0.22f);
HardwareComponent c3 = new Capacitor("cap3", 0.50f);
HardwareComponent c4 = new Capacitor("cap4", 0.75f);
HardwareComponent r1 = new Resistor("res1", 0.14f);
HardwareComponent r2 = new Resistor("res2", 0.18f);
HardwareComponent r3 = new Resistor("res3", 0.17f);
HardwareComponent r4 = new Resistor("res4", 0.10f);
pcb.placeComponent(c1);
I'm getting this error: The method placeComponent() in the type PCB is not applicable for the arguments (HardwareComponent)
No idea where to go from here, do I need to make a separate constructor for the class PCB or how do I pass the HardwareComponent to the method placeComponent?
Thank you in advance
Traian GEICU :
The method signature is faulty
public void placeComponent(<HardwareComponent> hw)
.
Try with
public void placeComponent(HardwareComponent hw)
