now how do I display text on JPanel?

Do you know what the API is? in general, they'll give methods for you to do most anything you can do in java. i'm not explaining how and just giving you a link to be rude, it's so that everytime you want to do something new in java, you can look at the API to see if there's a method that does what you want.

Yeong · « **Reply #47 on:** December 13, 2010, 08:37:46 pm »

thank you for the link.
I won't bother you no more....

lol you aren't bothering me! if you can't find something in the API i'd be glad to help. like if you want to display an image, and then after that you want to rotate it. and after that you want to make a racing game that scrolls. i can help you along there

"encoding" and "decoding" a string. you really aren't... for example, does this look recognizable?

Code: [Select]

{0171,0157,0165,040,0150,0141,0166,0145,040,0154,0157,0163,0164,040,0164,0150,0145,040,0147,0141,0155,0145,056}

i bet this does though:

Code: (translation) [Select]

you have lost the game.

to encode:

Code: [Select]


import java.util.*;

public class Array{

 public static void main(String[] args){
  Scanner reader = new Scanner(System.in);
  String str = reader.nextLine();
  String obfuscation = "{";
  for(int i = 0; i < str.length(); i++){
   obfuscation += "0" + Integer.toOctalString((int)str.charAt(i));
   if(i + 1 != str.length())
    obfuscation += ",";
  }
  obfuscation += "}";
  System.out.println("encoded: " + obfuscation);
 }

}

to decode:

Code: [Select]

public class Array2{

 public static void main(String[] args){
  int[] ints = <output from first program>;
  for(int i: ints)
   System.out.print((char)i);
 }

}

Damnit I lost

Nice code, though.

insult generator! they're actually pretty lame.. i tried.

Code: [Select]

import java.util.*;

public class Insult{
 static Random r = new Random();
 public static void main(String[] args){
  System.out.println(randomStart() + randomAdj() + randomNoun() + "you " + randomPersonAdj() + randomInsult() + ". " + randomEnd());
  Scanner reader = new Scanner(System.in);
  System.out.println("Want another opinion? (y/n)");
  if(reader.nextLine().equalsIgnoreCase("y"))
   main(null);
 }

 public static String randomStart(){
  String[] starts = {"What is this ","Why would you leave this ",};
  return starts[r.nextInt(2)];
 }
 public static String randomAdj(){
  String[] adj = {"stupid ","blatant ","moronic ","abominable "};
  return adj[r.nextInt(4)];
 }
 public static String randomNoun(){
  String[] noun = {"piece of garbage ","filth ","waste "};
  return noun[r.nextInt(3)];
 }
 public static String randomPersonAdj(){
  String[] adj = {"deficient ","senseless ","rash ","puerile ","nonsensical ","thick headed ","fat ","pointless ","obtuse "};
  return adj[r.nextInt(9)];
 }
 public static String randomInsult(){
  String[] insults = {"crud of the gene pool","failure","waste of breath","imbecile","incompetent monkey"};
  return insults[r.nextInt(5)];
 }
 public static String randomEnd(){
  String[] ends = {"Get lost.","Go climb a mountain.","Why don't you leave?","Just stop. Stop it now.","Seriously? Vamoose.","The Game."};
  return ends[r.nextInt(6)];
 }
}

for example:
Why would you leave this blatant piece of garbage you thick headed failure. Go climb a mountain.

Someone was mentioning JFrame programs, right?

Code: [Select]

import javax.swing.*;

public class HelloWorldSwing
{
 public static void main(String args[])
 {
  JFrame frame = new JFrame("Hello");
  JLabel label = new JLabel("Hello, Swing World");
  frame.getContentPane().add(label); 
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.pack();
  frame.setVisible(true);
 }
}

I coded a bit of JFrame yesterday, I'll post a JFrame numbar generator later

What's JFrame? Is it a derivative of java or is it a library, like JQuery for JS?

It's like wxPython for python

Or Tkinter for Python

JFrame is a standard part of Java and it isn't a library.
It's used to created frames. (Hence its name)
Edit: ninja'd

I see, thanks for the info.

Munchor · « **Reply #58 on:** December 19, 2010, 04:52:20 pm »

The syntax is the same as Java, but it has more functions/commands to help you making GUI

Swing is a standard part of Java, actually
