Question

cliced ​​Ich möchte ein Pop-up hinzuzufügen, wenn eine der Tasten

Hier geklickt wird, ist der Code:

Dies ist die Unterklasse

public class Pajero extends Mobil implements ActionMobil{ 


    @Override 
    public void kecepatan() { 
     System.out.println("Mobil ngegas"); 
    } 

    @Override 
    public void rem() { 
     System.out.println("Mobil ngerem"); 
    } 

    @Override 
    public void belokKiri() { 
     System.out.println("Mobil belok kiri"); 
    } 

    @Override 
    public void belokKanan() { 
     System.out.println("Mobil belok kanan"); 
    } 

    @Override 
    public void percepatMobil() { 
     System.out.println("Mobil sekarang berjalan lebih cepat"); 
    } 

    @Override 
    public void perlambatMobil() { 
     System.out.println("Mobil sekarang berjalan lebih lambat"); 
    }

mobil Klasse

package Kendaraan; 
    public abstract class Mobil{ 
    public String merkMobil; 

    public void tampilTipe(){ 
     System.out.println("Pajero"); 
    } 
} 

actionMobil Klasse

package Kendaraan; 


public interface ActionMobil { 
    public void kecepatan(); 
    public void rem(); 
    public void belokKiri(); 
    public void belokKanan(); 

    public void percepatMobil(); 
    public void perlambatMobil(); 

    public void tampilTipe(); 
} 

Wie Sie sehen können, möchte ich die ControlMobil.percepat(); auf der BtnPercepat zeigen, und haben es auf dem optionpane auftauchen.

Answer 1

Für was ich denke, Sie versuchen zu erreichen, müssen Sie mehrere Dinge ändern. Die Option Fenster angezeigt werden kommt in der Methode, die Sie unter der Annahme, kommentierten, dass das Objekt ein Klassenfeld ist, in der Frame.java:

Main controlMobil2 = new Main(new Pajero()); 

private void BtnPercepatActionPerformed(java.awt.event.ActionEvent evt) {            
     /** Shows ControlMobil.percepat(); on optionpane when its clicked **/ 

     JOptionPane.showMessageDialog(this, controlMobil2.percepat()); 
} 

Das das percepat auf Haupt zwingt einen String zurück, Main.java:

public interface ActionMobil { 
    ... 
    public String percepatMobil(); 
    ... 
} 

Neben der Pajero Klasse:

String percepat(){ 
     return setir.percepatMobil(); 

} 

, der wiederum die Schnittstelle zwingt den String zurückzukehren, anstatt sie an die Konsole zu schreiben gedruckt werden:

public class Pajero extends Mobil implements ActionMobil{ 
    ... 

    @Override 
    public String percepatMobil() { 
     //System.out.println("Mobil sekarang berjalan lebih cepat"); 
     return "Mobil sekarang berjalan lebih cepat"; 
    } 

    ... 
} 

Als Nebenbemerkung geben die Namenskonventionen an, dass Variablen in Kleinbuchstaben beginnen sollten.
