Drawing a figure on Java

[Ice Brazuca]

Hey guy I am learning to create shapes and such using Drawable frame on java. I am trying to draw a yellow diamond shaped sign that inside of it has a drawing of a traffic light.

Here's my code.

import java.awt.*;
import jpb.*;

public class SignalAhead
{
  public static void main(String[] args)
  {
   
	DrawableFrame df = new DrawableFrame("Signal Ahead");
	df.show();
	df.setsize(200, 200);

	Graphics g = df.getGraphicsContext();

	int[] xOuter = {30, 100, 100, 170};
	int[] yOuter = {100, 30, 170, 100};
	
	g.setColor(Color.yellow);
	g.drawPolygon(xInner, yInner, xInner.length);
	g.fillPolygon(xInner, yInner, xInner.length);

	int[] xCoordinates(25, 100, 100, 165);
	int[] YCoordinates(100, 35, 165, 100);
	
	g.setColor(Color.black);
	g.drawPolygon(xCoordinates, yCoordinates, xCoordinates.length);

	int[] xCoordinatess(26, 100, 100, 164);
	int[] YCoordinatess(100, 36, 164, 100); 
	
	g.setColor(Color.black);
	g.drawPolygon(xCoordinatess, yCoordinatess, xCoordinatess.length);

	int[] xCoordinatesss(27, 100, 100, 163);
	int[] YCoordinatesss(100, 37, 163, 100);

	g.setColor(Color.black);
	g.drawPolygon(xCoordinatesss, yCoordinatesss, xCoordinatesss.length);

	int[] xCoordinatessss(28, 100, 100, 162);
	int[] YCoordinatessss(100, 38, 162, 100);

	g.setColor(Color.black);
	g.drawPolygon(xCoordinatessss, yCoordinatessss, xCoordinatessss.length);


	int[] xCoordinatesssss(29, 100, 100, 161);
	int[] YCoordinatesssss(100, 39, 161, 100);

	g.setColor(Color.black);
	g.drawPolygon(xCoordinatesssss, yCoordinatesssss, xCoordinatesssss.length);

	

	g.drawRect(75, 45, 46, 130);
	g.setColor(Color.black);
	g.fillRect(75, 45, 46, 130);

	g.drawOval(85, 55, 34, 34);
	g.drawOval(85, 95, 34, 34);
	g.drawOval(85, 135, 34, 34);

	g.setColor(Color.red);
	g.fillOval(85, 55, 34, 34);

	g.setColor(Color.yellow);
	g.fillOval(85, 95, 34, 34);

	g.setColor(Color.green);
	g.fillOval(85, 135, 34, 34);

  }
}    

I keep getting an error on lines 22. int[] xCoordinates(25, 100, 100, 165);

Can anyone tell me what I am doing wrong? I've searched everywhere on my book and I don't understand what's causing the problem.

That's not how you initialize an array, this is the correct way:

 int[] xOuter = {30, 100, 100, 170};

As a test run I am only trying to draw the yellow triangle. Here is what I have.

import java.awt.*;
import jpb.*;

public class SignalAhead
{
  public static void main(String[] args)
  {
   
 DrawableFrame df = new DrawableFrame("Signal Ahead");
 df.show();
 df.setSize(200, 200);

 Graphics g = df.getGraphicsContext();

 int[] xOuter = {0, 100, 100, 200};
 int[] yOuter = {100, 0, 200, 100};
 int[] xInner = {0, 100, 100, 200};
 int[] yInner = {100, 0, 200, 100};
 
 g.setColor(Color.black);
 g.drawPolygon(xOuter, yOuter, xOuter.length);
 
 g.setColor(Color.yellow);
 g.fillPolygon(xInner, yInner, xInner.length);
 
 df.repaint();
  }
}    

I keep getting the error SignalAhead.java uses or overrides a deprecated API.
Recomplie with -Xlint:deprecation for details.

Can anyone tell me what I might be doing wrong?

[Maneesh Godbole]

As the message indicates, you are using some method call which is now deprecated.

Recomplie with -Xlint:deprecation for details.

If you do this, it will tell you which method.

[Janeice DelVecchio]

Some class or method from the API you're using is old and the compiler is mad.

Recompile with the switch and it'll probably give you a clue which it is.

Ok guys here is currently my new code.

  import java.awt.*;
import java.awt.event.*;
import jpb.*;


public class SignalAhead
{
  public static void main(String[] args)
  {
   
 DrawableFrame df = new DrawableFrame("Signal Ahead");
 df.show();
 df.setSize(200, 200);

 Graphics g = df.getGraphicsContext();

 int[] xOuter = {0, 100, 200, 100};
 int[] yOuter = {100, 0, 100, 200};
 int[] xInner = {0, 95, 200, 95};
 int[] yInner = {100, 0, 100, 200};
 
 g.setColor(Color.black);
 g.drawPolygon(xOuter, yOuter, xOuter.length);
 
 g.setColor(Color.yellow);
 g.fillPolygon(xInner, yInner, xInner.length);
 
 df.repaint();
  }
}
  

I have to ignore the -Xlint error, because I need to make this program using the AWT.

Anyways I need for a black line going throught the diamond and the line has to fill in 5 pixels. I can't seem to be able to do this. And the current line I have only fills in 1 pixel and it only works on the right side of the diamond.
