好的,这就是我所拥有的
public class Register {
public String propertyID;
public String PPSNumber;
Register(String aPropertyID, String aPPSNumber) {
propertyID = aPropertyID;
PPSNumber = aPPSNumber;
}
public void setPPSNumber(String aPPSNumber) {
PPSNumber = aPPSNumber;
}
public String getPPSNumber() {
return PPSNumber;
}
public String getPropertyID() {
return propertyID;
}
}
然后我有这个
public static ArrayList<Register> registers = new ArrayList<Register>();
public static void main(String[] args) {
String userInput1 = "", userInput2 = "", userInput3 = "";
userInput1 = JOptionPane.showInputDialog("Enter your PPSNumber");
userInput2 = JOptionPane.showInputDialog("Enter your propID");
registers.add("number", "id");
}
我不明白为什么它不允许我添加到 ArrayList。有没有办法向 ArrayLists 添加类类型?
