关闭构造函数中的JFORF

Question

我对代码有一个小问题。我只希望如果在表单的构造函数部分中未满足条件，则不会显示jform。我尝试了this.dispose（）;并返回；this.setvisible（false）;但是表格仍显示。使用system.exit（0）;它关闭了完整的应用程序。如果有人能帮助我，真的很感激。

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

做类似的事情

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指出的那样，这很好。

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);
   } 
}
}
