数组到JLabel

Question

我有两个Java类包

• PK字符串
• 密码表

---

public class classWork {
    public String[] titleMenu={
        "A","B","C","D"
    };

    public int intOption;
}

我有菜单的JFrame

• 点击进入jframe A，

  B点击进入jframe B，

  C单击进入jframe C，

  D单击转到jframe D

和同一包JFram01其他框架包含JLabel 。

如何识别是否单击“ A”并显示该位置标签？

Answer 1

I dont understand your need. "A click A go jframe A" doesnot make sense.
if you want to go to another jFrame when clicking a label
Try this

    private void yourlabelMouseClicked(java.awt.event.MouseEvent evt) {
          //  either you can hide the current jFrame by setting 
            jFrame.setVisible(false);
            newjFrame.setVisible(True);
                    or
            make these jFrames in 2 different classes that make simple invocations
        }

Answer 2

据我了解，您可以在包中使用公共变量，并使用A，B，C ....上的点击事件在其中存储值。

然后从您想要的jfaram访问该信息

例如

public String pos ="";

A onclick event(){
   pos="A";
}


finally

if(pos.compareto("A")==0){
   jlabel.settext("A");
}
