So I already took the ap comp sci for my high school and was planning on taking the next programming class. Unfortunately, they have a lack of teachers in that department and decided to drop that class. As I have exhausted the computer science classes at my school would it be possible for me to take them at a community college? Any advice is appreciated.

So I am not the most experienced with android, but I do get enough to program basic apps. I have a game in mind that would require a grid or tile feature. This is particularly annoying because it would be so incredibly easy in standard Java Swing. But anywho. I know that android has a GridLayout that I could use but when I tried to programmatically add buttons on runtime it didn't work. I don't need to do it at runtime but i could find a better alternative as it did work otherwise. The grid needs to be able to let the buttons "fall" but I can implement that part, so it needs to allow buttons to be removed and set in different coords. I don't know if there is a layout I could use or something of that sort. Thanks, and any code or link is appreciated.

So I'm making this site where it shows different photos and you choose which one that relates most to the question....kinda dumb i know but im bored as ****...For example, it would show four photos and the question is who looks the most ratchet? You obviously choose the black guy (jk..well..). So do you guys (or gals) have any good questions for the site...

Okay, I know this is a common problem with downloading Android Studio in Windows, but after I downloaded and opened Android Studio I got the error message: "No JVM installation found. Please intall a 64-bit JDK. If you already have a JDK installed, define a JAVA_HOME variable in Computer > System Properties > System Settings > Environment Variables."... So I did this, or at least I think I did. I typed Environment Variables into the Start Task Manager and opened it up. Then I added the JAVA_HOME variable with the path, C:\Program Files (x86)\Java\jdk1.7.0_21...all the examples I see have Program Files, instead of Program Files (x86)...I know the difference, just wanted to tell you everything. Anyway, after I did that it still shows the error message. Thanks in advance.

So I downloaded the android app dev kit from their website. I was just wondering if I could use those icons in my site without any problems. Thanks

Ok so just created a facebook app and chose to use the heroku server thing...

Ok so i downloaded the heroku toolbelt...I followed the instructions...

1)when i type in my email and password it doesn't create the SSH public key...

then when i do other things it says it can't find that directory...please help

So I want to make either an android or iPhone 2d game like the diplomacy board game...

Also I want to be able to have players join have the game play through the Internet...

I know HTML and php and JavaScript and a tiny bit of java...any tutorials recommendations?

Also I have windows which might be a problem for iPhone apps I think...

Ok i was wondering...if i made a chat website using xampp/localhost...

then if i downloaded the website on 2 computers....

is there any way i could basically view the website on 2 computers have them contact each other???

Ok I dont want to know what softwares there are out there to find this....I already know them....I just want to know if its possible to create a program that reads the CPU temp and if so with what language...I think I saw something about vbscript but I dont know....any resources would be greatly appreciated!!!

Ok so i have installed the android sdk and i have eclipse installed. but when i try to install the adt, it doesn't work.. I think i need eclipse helios and i have eclipse europa....now should i get helios, and if i do should i just move the eclipse folder to the recycling bin?

So im making this notepad text editor type thing and i want to add a status bar at the bottom that dynamicly updates the number of characters in the jtextarea....i have this code but it produces a lot of confusing errors/im new to this..

Ok so im making a solar cooker...it cant use any electricity and no solar panels...im going to use a cooking pan but should i use aluminum foil on top to make it hotter? And if i do should i paint it black since i know black heats up quickly...

thanks in advance

Ok, I feel like I'm going to start a great big giant argument when I ask this but I feel it should be asked. So I'm currently learning PHP but I want to learn something else on the side, so when PHP is boring I can go to it and visa versa. I have heard of RoR and researched and people are either saying that its a really big waste and that you should just stick to PHP or that its 'fun' to code. So I feel like I want to be 'entertained' when I'm coding but if it is a really big waste of time than screw it why learn it?

Is the reaction of baking soda and vinegar considered a biotechnology? If not could you list a few examples, thanks.

How does websites like Hulu or Fandango get their videos right after they come out on television, or how do they get their movies and trailors for that matter. The reason I'm asking, is because I want to create a website like those but dont know how to get them.

I am just trying to start php -also any tutorials recommended- and I am trying to make a message board for practice. It works but when I type something new the previous message goes away. I understand why this happens just dont know how to fix it...

I have a html file and a php file

index.html-

<!DOCTYPE html>

<html><body>

<h4><u>Message Board</u></h4>

<form action="myfirstfile.php" method="post">

<input name="message" type="text" />

<input type="submit" name="formSubmit" value="Submit" style="height: 0px; width: 0px; border: none; padding: 0px;" hidefocus="true" />

</form>

</body>

</html>

myfirstfile.php-

<?php

include 'index.html';

$message = $_POST['message'];

echo "$message";

?>

Ok so the goal of this program is to find the two factors in a polynomial ( for example: x^2 + 7x + 12..

what two numbers would be multiplied to get a*c(12) and added to get b(7)....the answers would be 4 and 3...) so here is my program...

#include <iostream>

using namespace std;

void find(a, b);

float a;

float b;

float c;

float d;

int main(){

cout << "What is the 1st Value?" << endl;

cin >> a;

cout << "What is the 2nd Value?" << endl;

cin >> b;

find(a, b);

}

void find(a, b){

int x = -500;

float i = -1000;

float p = -1000;

while(x<100000){

if(i*p == e || i+p == f){

cout << "The two numbers are " << i << " and " << p << endl;

}

else{

x++;

i+=.01;

p += .01;

}

}

}

So what my goal is for the program: Guessing game that the user inputs numbers (max 50), if its too high or too low it will tell you and then it stores your score (if its a highscore) in a file called highScore.txt... so I got the high and low part to work but i cant get the highscore thing to work (a little more complicated but...)

heres my code:

import java.util.*;

import java.io.*;

import java.lang.*;

public class Game {

public static void main(String[] args) throws IOException {

//Variables

Scanner inp = new Scanner(System.in);

int rand = (int)(Math.random() * 1000) +1;

int tries = 0;

//Stuff for Highscore

File f = new File("highScore.txt");

FileWriter fw = new FileWriter(f);

BufferedWriter op = new BufferedWriter(fw);

//File Writer Stuff

if(!f.exists());{

f.createNewFile();

}

//File Reader Stuff

FileInputStream ifs = new FileInputStream(f);

DataInputStream in = new DataInputStream(ifs);

BufferedReader br = new BufferedReader(new InputStreamReader(in));

String str;

//Convertng String to Int and reading it

str = br.readLine();

int highScore =Integer.parseInt(str);

in.close();

//Meat of the Program

//

//

//

//Meat of the Program

System.out.println("Guess a number 1-1000: ");

while(tries < 50){

int g = inp.nextInt();

if(g == rand){

tries++;

System.out.println("Wow,Only took you " + tries + " tries (Sarcastically).");

//High Score Checker

if(tries < highScore){

op.write(highScore);

op.close();

System.out.println("NEW HIGHSCORE!!!");

}

System.out.println("Your Score: " + tries);

System.out.println("High Score: " + highScore);

}

if(g < rand){

tries++;

System.out.println("Higher");

}

if(g > rand){

tries++;

System.out.println("Lower");

}

}

ok, earlier i asked one question about thenewBoston's java gameProgramming tutorials but i have another here's code it just doesnt work its weird...but first the two classes used are bucky and Screen...

it runs but doesnt show the text and then displays tons of errors in the output

bucky:

import java.awt.*;

import javax.swing.JFrame;

public class bucky extends JFrame{

public static void main(String[] args){

DisplayMode dm = new DisplayMode(800, 600, 16, DisplayMode.REFRESH_RATE_UNKNOWN);

bucky b = new bucky();

b.run(dm);

}

public void run(DisplayMode dm){

setBackground(Color.PINK);

setForeground(Color.WHITE);

setFont(new Font("Arial", Font.PLAIN, 24));

Screen s = new Screen();

try{

s.setFullScreen(dm, this);

try{

Thread.sleep(5000);

}

catch(Exception ex){

}

}

finally{

s.restoreScreen();

}

}

public void paint(Graphics g){

if(g instanceof Graphics2D){

Graphics2D g2 = (Graphics2D)g;

g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

}

g.drawString("This is gonna be amazing", 200, 200);

}

}

Screen:

import java.awt.*;

import javax.swing.JFrame;

public class Screen {

private GraphicsDevice gd;

public Screen(){

GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();

gd = env.getDefaultScreenDevice();

}

public void setFullScreen(DisplayMode dm, JFrame window){

window.setUndecorated(true);

window.setResizable(false);

gd.setFullScreenWindow(window);

if(dm != null && gd.isDisplayChangeSupported()){

try{

gd.setDisplayMode(dm);

}

catch(Exception ex){

}

}

}

public Window getFullScreenWindow(){

return gd.getFullScreenWindow();

}

public void restoreScreen(){

Window w = gd.getFullScreenWindow();

if(w != null){

w.dispose();

}

gd.setFullScreenWindow(null);

}

}

from thenewBoston tutorials on java gameDevelopment on how to create a screen...

so my problem is that my when i was following the newBoston tutorials my code didnt work while his did, i was kinda confused and tried different things but had no real idea of what to do because i never learned the thing before...there are 2 classes called bucky and Apple...

the error occurs at b.run(dm);

here is the bucky code...

import java.awt.*;

import javax.swing.JFrame;

public class bucky extends JFrame{

public static void main(String[] args){

DisplayMode dm = new DisplayMode(800, 600, 16, DisplayMode.REFRESH_RATE_UNKNOWN){

bucky b = new bucky();

b.run(dm);

}

public void run(DisplayMode dm){

setBackground(Color.PINK);

setForeground(Color.WHITE);

setFont(new Font("Arial", Font.PLAIN, 24));

Screen s = new Screen();

try{

s.setFullScreen(dm, this);

try{

Thread.sleep(5000);

}

catch(Exception ex){

}

}

finally{

s.restoreScreen();

}

}

public void paint(Graphics g){

g.drawString("This is gonna be amazing", 200, 200);

}

}

i dont know if you need the Apple code but here it is...

eclipse shows no errors on this one...

import java.awt.*;

import javax.swing.JFrame;

public class Screen {

private GraphicsDevice gd;

public Screen(){

GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();

gd = env.getDefaultScreenDevice();

}

public void setFullScreen(DisplayMode dm, JFrame window){

window.setUndecorated(true);

window.setResizable(false);

gd.setFullScreenWindow(window);

if(dm != null && gd.isDisplayChangeSupported()){

try{

gd.setDisplayMode(dm);

}

catch(Exception ex){

}

}

}

public Window getFullScreenWindow(){

return gd.getFullScreenWindow();

}

public void restoreScreen(){

Window w = gd.getFullScreenWindow();

if(w != null){

w.dispose();

}

gd.setFullScreenWindow(null);

}

}
