Save the day!

Hi!
Do you hate it, that anybody can come, and read what you have written? Well, today I will show you a simple way, to make a scrambler! I have not worked out, how to make a de-scramler, but we will survive! Here is the CODE:

/*
* Made by pepluser
* pepluser.blogspot.com
*
*/
package testgui;

import java.util.Scanner;


/**
*
* @author Peter
*/
public class Testgui {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
char c1, c2, c3, c4;

System.out.print("Enter word to scramble: ");
c1 = sc.findInLine(".").charAt(0);
c2 = sc.findInLine(".").charAt(0);
c3 = sc.findInLine(".").charAt(0);
c4 = sc.findInLine(".").charAt(0);

System.out.println(c3 + " " + c1 + " " + c4 + " " + c2);
      }
}

Well, it should work, i hope you have fun, and you can modify it, and add stuff! See You! :)

Randomising :)

Hi!
One of the things I like most in Java, is Random. I like it because I can make it do anything! Here is the code of a basic randomizer! CODE:

import java.util.Random;                           // imports the Random number generator

class randomizer {

public static void main(String args[]) {
Random rn = new Randon();                    
int random;

random = rn.nextInt(10);                          // tells the compiler, in what range of number shoud it generate.
System.out.println(random);                     // displays the number

    }
}

This is a simple code. But you can use the if , to make it more enchanced!

Whats WRONG?!

Hi!
I have been working on this question for a few days now. I don`t know whats wrong in my code! I have scanned the internet and on every site, the code is the same, as in what I have made! I need help! You can tell me in the comments, or you can go to Yahoo Answers, and answer it there! Thanks for your help! And here is the code:

/*
* Made by pepluser.
* pepluser.blogspot.com
*/
package test2;

import javax.swing.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;



/**
*
* @author Peter
*/
public class Test2 implements ActionListener {

/**
* @param args the command line arguments
*/


public static void main(String[] args) {
ActionListener a = null;

JFrame f1;
JButton button;

f1 = new JFrame("Test2");


button = new JButton("Hello");
button.addActionListener(a);

f1.add(button);
f1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f1.setVisible(true);


}



public void actionPerformed(ActionEvent a) {
button.setText("Goodbye");


}


}





I made this in NetBeanes, a free java IDE! Thanks for your help!
