내 코드에 문제가있어서 해결할 수없는 것 같습니다. 버튼을 제출할 때 java/GWT의 배열 목록에 고객 데이터를 추가하고 싶습니다.GWT/JAVA 잡히지 않은 예외가
내가 데이터를 추가하는 양식.
ok.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
if (!voornaamTB.getText().equalsIgnoreCase("") && !achternaamTB.getText().equalsIgnoreCase("") && !emailTB.getText().equalsIgnoreCase("") && !geboortedatumTB.getText().equalsIgnoreCase("")) {
boolean addVG;
System.out.println(voornaamTB.getText());
System.out.println(tussenvoegselTB.getText());
System.out.println(achternaamTB.getText());
System.out.println(emailTB.getText());
System.out.println(geboortedatumTB.getText());
--> the error is generated here addVG = VGC.addVakantieganger(voornaamTB.getText(), tussenvoegselTB.getText(), achternaamTB.getText(), emailTB.getText(), geboortedatumTB.getText());
if (addVG) {
Window.alert("Vakantieganger toegevoegd.");
} else {
Window.alert("Vakantieganger niet toegevoegd.");
}
} else {
voornaamTB.addStyleName("invalide-TextBox");
tussenvoegselTB.addStyleName("invalide-TextBox");
achternaamTB.addStyleName("invalide-TextBox");
emailTB.addStyleName("invalide-TextBox");
geboortedatumTB.addStyleName("invalide-TextBox");
}
}
});
컨트롤러 클래스.
import java.util.ArrayList;
import com.vakantievibes.client.domein.Vakantieganger;
public class VakantiegangerController {
private String msg;
private ArrayList<Vakantieganger> vakantiegangers = new ArrayList<Vakantieganger>();
public VakantiegangerController(){
}
@SuppressWarnings("static-access")
public boolean heeftVakantieganger(String email) {
boolean result = false;
for (Vakantieganger v : vakantiegangers) {
if (v.getEmail().equalsIgnoreCase(email)){
result = true;
}
}
return result;
}
public boolean addVakantieganger(String voornaam, String tussenvoegsel, String achternaam, String email, String geboortedatum) {
//boolean result = false;
//if (!heeftVakantieganger(email)) {
Vakantieganger v = new Vakantieganger(voornaam, tussenvoegsel, achternaam, email, geboortedatum);
vakantiegangers.add(v);
boolean result = true;
System.out.println("klant toegevoegd");
//}
return result;
}
}
메소드 addVakantieganger를 사용하면 데이터를 arraylist에 추가해야합니다. 그러나 그것은 사실을 다시 형태로보고해야한다고 생각하지 않습니다. ! heeftVakantieganger (전자 메일)는 해당 사람이 이미 배열 목록에 있지만 검사 목적으로 사용하지 않는지 확인해야합니다.
이클립스에서 오류가 발생합니다.
