Provides two simple solutions, one using jpanel and the other using jlabel.

1. jpanel (source code)

Package Oo; import Java. AWT. graphics; import Java. AWT. image; import Java. io. file; import javax. swing. imageicon; import javax. swing. jframe; import javax. swing. jpanel; public class drawing {jframe = new jframe (); public static jpanel gimage = NULL; public drawing () {initframe () ;}// initialization window public void initframe () {// use jpanel to add the background image gimage = new jpanel () {protected void paintcomponent (Graphics g) {imageicon icon = new imageicon ("image \ benbenla.jpg "); image IMG = icon. getimage (); G. drawimage (IMG, 0, 0, icon. geticonwidth (), icon. geticonheight (), icon. getimageobserver (); jframe. setsize (icon. geticonwidth (), icon. geticonheight () ;}}; jframe. settitle ("test background image"); jframe. add (gimage); jframe. pack (); jframe. setvisible (true); jframe. setdefaclocloseoperation (jframe. exit_on_close);} public static void main (string [] ARGs) {New Drawing ();}}

2. jlabel source code

Package swing. draw; import Java. AWT. image; import javax. swing. imageicon; import javax. swing. jframe; import javax. swing. jlabel;/** use jlabel to construct images */public class drawing2 {jlabel jlpic = new jlabel (); jframe = new jframe (); Public drawing2 () {init1frame ();} public void init1frame () {imageicon = new imageicon ("image \ benla.jpg"); icon. setimage (icon. getimage (). getscaledinstance (icon. geticonwidth (), icon. geticonheight (), image. scale_default); system. out. println (icon. geticonheight () + "" + icon. geticonwidth (); jlpic. setbounds (0, 0, 1366,768); jlpic. sethorizontalalignment (0); jlpic. seticon (icon); jframe. setsize (1366,768); jframe. add (jlpic); jframe. pack (); jframe. setdefaclocloseoperation (jframe. exit_on_close); jframe. setvisible (true);} public static void main (string ARGs []) {New drawing2 ();}}
