Answer 1

모든 자바 프로그램이 주요 방법에서 시작 :

public static void main(String[] args) { 
    java.awt.EventQueue.invokeLater(new Runnable() { 
      public void run() { 
       FrameWithBorderLayout frame = new FrameWithBorderLayout(); 
       frame.setVisible(true); 
      } 
    }); 
} 

프레임 클래스에 추가하십시오.

Answer 2

FrameWithBorderLayout frameTest = new FrameWithBorderLayout(); 
frameTest.setVisible(true);
