public class A extends Jpanel{
public void a(){
public static void main(String[] a){
}
}
class B extends Jpanel{
}
如何在A的事件监听器中使用B的数据？
------解决方案--------------------
- Java code
public class A extends JPanel{ private B b = new B(); public void a(){ System.out.println(b.getData()); } public static void main(String[] args){ } }class B extends JPanel{ private Object o = new Object(); public Object getData() { return o; } }
------解决方案--------------------
- Java code
import javax.swing.*;@SuppressWarnings("serial")public class A extends JPanel { private B b; public A(){ b = new B(); } public void a() { b.gg(); } public static void main(String[] a) { A aa = new A(); aa.a(); }}@SuppressWarnings("serial")class B extends JPanel { public void gg(){ System.out.println("abcdefg"); }}
