java - How To Add JLabel to Already Existing Jframe? -

lol dont know if worded right

i new programmer , code main class:

package culminatingnew;

import java.awt.borderlayout; import java.awt.color; import java.awt.container; import java.awt.dimension; import javax.swing.jframe; import javax.swing.jlabel; import javax.swing.joptionpane;  import javax.swing.jtextfield;    public class culminatingnew {    public static void main(string[] args) {    container container = null;   jframe jframe = new jframe("math adventure"); jframe.setdefaultcloseoperation(jframe.exit_on_close); jframe.setlocationrelativeto(null); jframe.setbounds (150, 0, 1000, 1000); jframe.setbackground(color.blue); jframe.setvisible(true);    jlabel labeltext = new jlabel("welcome!");           jframe.getcontentpane().add(new characterchoose());//  jframe.setvisible(true);  jframe.getcontentpane().add(labeltext);   jframe.setvisible(true); 

so basically, i'm making game. in class in assignment package characterchoose, user greeted picture of character. want add text same screen saying "welcome", whenever try ignores characterchoose screen , opens new blank frame says "welcome". there way fix this?

gui's not linear/procedural programs, event driven, is, happens , respond it.

instead, maybe consider using button saying "continue" or something, user must press, once pressed, can present next view.

i'd recommend having @ cardlayout easier management of switching between views.

see how use buttons, check boxes, , radio buttons, how write action listeners , how use cardlayout more details
