How to start java programming Videos

+zoranhacker oh lol I forgot to write new Boot(); in the main function

My Package Is DATA And My Class Is Main

package DATA;import static org.lwjgl.opengl.GL11.GL_MODELVIEW;import static org.lwjgl.opengl.GL11.GL_PROJECTION;import static org.lwjgl.opengl.GL11.GL_QUADS;import static org.lwjgl.opengl.GL11.glBegin;import static org.lwjgl.opengl.GL11.glEnd;import static org.lwjgl.opengl.GL11.glLoadIdentity;import static org.lwjgl.opengl.GL11.glMatrixMode;import static org.lwjgl.opengl.GL11.glOrtho;import static org.lwjgl.opengl.GL11.glVertex2f;import org.lwjgl.LWJGLException;import org.lwjgl.opengl.Display;import org.lwjgl.opengl.DisplayMode;public class Main { public static final int WIDTH = 800, HEIGHT = 600; public static void main(String[] args) { Display.setTitle("Black Screen"); try { Display.setDisplayModeAndFullscreen(new DisplayMode(WIDTH, HEIGHT)); Display.create(); } catch (LWJGLException e) { e.printStackTrace(); } glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(0, WIDTH, HEIGHT, 0, 1, -1); glMatrixMode(GL_MODELVIEW); while (!Display.isCloseRequested()) { Display.update(); Display.sync(60); DrawQuad(100, 100, 150, 150); DrawQuad(250, 250, 150, 150); } } public static void DrawQuad(float x, float y, float width, float height) { glBegin(GL_QUADS); glVertex2f(x, y); glVertex2f(x + width, y); glVertex2f(x + width, y + height); glVertex2f(x, y + height); glEnd(); }}

import static org.lwjgl.opengl.GL11.*;

+Danny Peak type this import in your imports list it will fix the problem

+JINGCHEN LIU i do, and thankyou

+Luke Charles if you works on Mac, add this line as the first line in the while loop.GL11.glClear(GL11.GL_COLOR_BUFFER_BIT); //added for MacNeed to importimport org.lwjgl.opengl.GL11;I had the similar issue as my screen keeps on flashing this line to clear the screen before you update the display.

Could you copy/paste your code here?

i thought i solved it but it still flickers

it worked a few hours later it might have been slow wifi... but now i have a new problem, i have a grid full of grass tiles but they flicker a lot! do have any idea why this might be happening?

+Luke Charles It's working for me, did you type in the URL correctly?

It really makes no difference. Since for example dividing x by 4 is exactly the same as multiplying by 1/4. Likewise for addition and subtraction. x - 3 is the same as x + - 3. No difference. Parenthesis and Indices make a difference though.

when i start a project, under source, theres nothing else its just a source folder and i havent figured out how to get the right stuff to show up, its not automatically creating a class by the same name of the file. any suggestions?

holy shit after watching like the first 2 min of the video, i noticed our keyboards don't have the elementary school division sign...wtf. i have been using the computer since like a little baby... how did i not c this.

order operations parethisis , exponents , multiplication or division wich ever one comes first , then addition or sabtraction wich ever one comes first . its like p e m or d a or s

@callofdutyguy12345 At school (both primary and secondary) we were taught BIDMAS (Brackets, Indices, Devision, Multiplication, Addition, Subtraction).

no, you can't TYPE. You should worry about standard spelling before you attempt to cast your stones. I learned that word in 3rd grade man.

@MrNomSauce Oh Yes,yes,yes. My mistake. I was actually taught BIMDAS,pretty much BIDMAS,except the M and D are switched.

Everyone remember this: GEMDAS Grouping Symbols Exponents Multiplication Division Addition Subtraction

Remember this as well, PEMDAS Parentheses Exponents Multiplication Division Addition Subtraction, :D

you should really make a playlist so with all those videos so it's easy'er to find around

Couldnt you start with division if division was left of multiplication in your example?

Dud i already mastered batch programing can u tell me which videos i should skip?

thanks am so far out of school I have forgotten my maths this really helps :-)

% is not Java specific. I know it is in C and C++ (and probably others as well)

@MrNomSauce Nope. Remember "MDAS" Multiplication Division Addition Subtraction

So is Exponents excluded from the Order of Operations in Java Programming?

or subtraction before addition if Subtraction was left of addition?

Can I have this presentation? ,because i'm going to translate it to Arabic as a lot of Arabic people interested in Lambda.

+Jake Pietruszewski Yes, that's what it seems to be.

+Hector Sanchez needs graphics environment
