java - JFrame does not appear -

-

i'm using intelij idea platform.

i have following code:

package gui.test;  import javax.swing.*;  public class frame extends jframe{           frame(){}  public void main (string[] args){      new frame(); }  }

i expected see jframe after compiling code, nothing appeared. kind of problem can be?

frames not visible default--use the

setvisible(true);

method in order display frames. might want take @ other options such as

setsize(int width, int height);

method resize frame,

setlocation(int xloc, int yloc);

to move frame, and

settitle(string title);

to set title of component.

aside, practice use variable hold components can manipulated when needed.
