在构造函数中关闭Jform

Question

我对代码有个小问题。我只想在form.Outside的构造函数部分不满足条件的情况下不显示J表单--构造函数dispose()、返回和setVisible(false)都正常工作。我尝试过this.dispose()；并返回；和this.setVisible(false)；但是表单仍然显示。使用System.exit(0)；它关闭了整个应用程序。如果有人能帮我做这件事我会很感激的。

public class OrderGUI extends javax.swing.JFrame {

public OrderGUI(Customer cust, Date dt, Time t) throws FileNotFoundException, IOException, ClassNotFoundException {
    this();
if(condition)
{
/////do not initialize the Jform
}else{//// run rest of the code}
}

Answer 1

做这样的事

public class OrderGUI extends javax.swing.JFrame {
    public OrderGUI(Customer cust, Date dt, Time t) throws FileNotFoundException, IOException, ClassNotFoundException {
       this();
    }

   @Override
   public void setVisible(boolean val){
       if(!condition){
           super.setVisible(val);
       } 
   }
}

Answer 2

正如Subash所指出的，这是完美的。

public class OrderGUI extends javax.swing.JFrame {
public OrderGUI(Customer cust, Date dt, Time t) throws FileNotFoundException, IOException, ClassNotFoundException {
   this();
}

@Override
public void setVisible(boolean val){
   if(!condition){
       super.setVisible(val);
   } 
}
}
