The PIN right now is 2995
This program will ask the person for a password and if they get it right the will be shown some info. Fully commented!
[code2=java]import javax.swing.JOptionPane;
public class password {
public static void password (){
String password = "Potato";//This is the actual password
String input = (JOptionPane.showInputDialog("Insert Password:"));// This is the question asked

JOptionPane.showMessageDialog(null, "Access Granted");//If you get it right
JOptionPane.showMessageDialog(null, "This is the information:BLAH BLAH BLAH BLAH BLAH BLAH");//The information
}else{

Like, is it written in a language that can run from the computer itself, or does it have to have an operating system like Windows or Mac? Like, can I write a bootloader and in the end open the Java Framework and be able to run .jar files on this system?
What I am trying to do is make a program that, when a person clicks a button, it'll add a tab page to the JTabbedPane, and add another JFrame to the tab page. I think I know how to do it, by using
Code:
JTabbedPane.addTab(otherClassWithJFrame);
If this won't work, can anyone tell me otherwise, and how would I make it where 'otherClassWithJFrame' had no title bar? Any help will be greatly appreciated. Thank you and have an amazing day!
Why are all the topics for java on the last page unavailable? <!-- s:?: --><img src="{SMILIES_PATH}/icon_question.gif" alt=":?:" title="Question" /><!-- s:?: -->
This is more of a control than a code snippet, but I wanted to share my "editable label" control anyway.
The premise behind this control is the idea that users should be able to view and edit information; however, the ability to edit should remain non-intrusive. This is especially useful for people like on-phone tech-support who often need to view information but very rarely need to edit it.
The control consists of the following items
-A FlowLayoutPanel
-Two Labels
-A TextBox
Here is the code behind the control:

This is more of an explanatory program than a practical. It will count to 100 and show you when it it finished.
[code2=java]import java.util.Scanner;
public class New {
static Scanner input = new Scanner(System.in);
public static void main(String[]args){
countNumber();}
public static void countNumber(){
int i = 0;
while (i <= 100){//The while statement says that this will repeat 100 times
System.out.println(i);
i++;
if(i == 101){
System.out.println("I now equals 100");
}
}
}
}[/code2]
p.s. Sorry that it does not tell you exactly what is doing
This code will generate 100 random numbers (can be changed) from 0 to 6. Then it will count how many of each number there was. This is a take on Brandon's Random Number Generator on YouTube
------------------------------------------------------
[code2=java]import java.util.Random;

int three = 0;
int four = 0;
int five = 0;
int six = 0;
int nill = 0;
int i = 0;
/*To change the amount of random numbers generated
* change the statement below from
* while (i <= 100); to
* while (i <= YourAmountOfNumbers);
*/
while (i <= 100){
Random rnd = new Random();
System.out.println(rnd.nextInt(7));
if ((rnd.nextInt(7) > 0.99) & rnd.nextInt(7) < 1.1){
one = one + 1;
}
