我试图将硬件组件添加到包含对象阵列的PCB上,但无法将对象传递给该阵列。这是我的第一个Java项目,所以在这里是新手。请帮忙!
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);
}
而我的主
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);
我收到此错误:
PCB类型中的方法placeComponent()不适用于自变量(HardwareComponent)
不知道从哪里开始,我是否需要为类PCB创建一个单独的构造函数,或者如何将HardwareComponent传递给placeComponent方法?
先感谢您
最佳答案
方法签名有误public void placeComponent(<HardwareComponent> hw)
。
试试看public void placeComponent(HardwareComponent hw)
关于java - PCB类型中的方法placeComponent()不适用于自变量(HardwareComponent),我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/60993541/
