  • $\color{#D29922}\textsf{\Large⚠\kern{0.2cm}\normalsize Warning}$: The Window is resizable. reference the Problem

  public class test {
      public static void main(String[] args){
          JFrame frame= new JFrame(); //create a frame
          frame.setSize(800,800);
          frame.setVisible(true);//making it visible
