Making a Stop sign

[remedys]

import javax.swing.*;
 
import java.awt.*;
public class StopSign extends JFrame {
 
public void paint(Graphics gr){
	super.paint(gr);
	int[] xPoints = {90, 180, 300, 390, 390, 300, 180, 90 };
	int[] yPoints = {180, 90, 90,  180,  300, 390, 390, 300 };
	int numPoints = 8;
	gr.drawPolygon(xPoints, yPoints, xPoints.length);
	gr.setColor(Color.RED);
	gr.fillPolygon(xPoints, yPoints, numPoints);
	int[] xPoints1 = {100, 190, 290, 380, 380, 290, 190, 100 };
	int[] yPoints1 = {190, 100, 100,  190,  290, 380, 380, 290 };
	int numPoints1 = 8;
	gr.drawPolygon(xPoints1, yPoints1, xPoints1.length);
	gr.setColor(Color.white);
	gr.fillPolygon(xPoints1, yPoints1, numPoints1);
	int[] xPoints2 = {120, 200, 280, 360, 360, 280, 200, 120 };
	int[] yPoints2 = {200, 120, 120,  200,  280, 360, 360, 280 };
	int numPoints2 = 8;
	gr.drawPolygon(xPoints2, yPoints2, xPoints2.length);
	gr.setColor(Color.red);
	gr.fillPolygon(xPoints2, yPoints2, numPoints2);
}
 
public static void main(String[] args){
	StopSign frame = new StopSign();
	frame.setSize(500,500);
	frame.setVisible(true);
 
}
}

So i made a stop sign using the following code. However, i need to put the word STOP in the middle of it ... I don't know how to put a the word on top of the polygon its self.

how to put a the word on top of the polygon its self.

Use the Graphic class's drawString() method.

import javax.swing.*;
import java.awt.*;
public class StopSign extends JFrame {
String Stop = new String("STOP");
public void paint(Graphics gr){
	super.paint(gr);
	int[] xPoints = {90, 180, 300, 390, 390, 300, 180, 90 };
	int[] yPoints = {180, 90, 90,  180,  300, 390, 390, 300 };
	int numPoints = 8;
	gr.drawPolygon(xPoints, yPoints, xPoints.length);
	gr.setColor(Color.RED);
	gr.fillPolygon(xPoints, yPoints, numPoints);
	int[] xPoints1 = {100, 190, 290, 380, 380, 290, 190, 100 };
	int[] yPoints1 = {190, 100, 100,  190,  290, 380, 380, 290 };
	int numPoints1 = 8;
	gr.drawPolygon(xPoints1, yPoints1, xPoints1.length);
	gr.setColor(Color.white);
	gr.fillPolygon(xPoints1, yPoints1, numPoints1);
	int[] xPoints2 = {120, 200, 280, 360, 360, 280, 200, 120 };
	int[] yPoints2 = {200, 120, 120,  200,  280, 360, 360, 280 };
	int numPoints2 = 8;
	gr.drawPolygon(xPoints2, yPoints2, xPoints2.length);
	gr.setColor(Color.red);
	gr.fillPolygon(xPoints2, yPoints2, numPoints2);
}
public void paint2(Graphics gr){
	super.paint(gr);
	gr.drawString(Stop, 0, 0);
	gr.setFont(new Font("Arial", Font.BOLD, 22)); 
	gr.setColor(Color.blue);
}
public static void main(String[] args){
	StopSign frame = new StopSign();
	frame.setSize(500,500);
	frame.setVisible(true);
}
}

I used this code to just see if STOP would appear in the JFrame but it didnt...

Where is the paint2() method called? If a method is not called, it won't be executed.

Put all the code in the paint() method.

import javax.swing.*;
import java.awt.*;
public class StopSign extends JFrame {
String Stop = new String("STOP");
public void paint(Graphics gr){
	super.paint(gr);
	int[] xPoints = {90, 180, 300, 390, 390, 300, 180, 90 };
	int[] yPoints = {180, 90, 90,  180,  300, 390, 390, 300 };
	int numPoints = 8;
	gr.drawPolygon(xPoints, yPoints, xPoints.length);
	gr.setColor(Color.RED);
	gr.fillPolygon(xPoints, yPoints, numPoints);
	int[] xPoints1 = {100, 190, 290, 380, 380, 290, 190, 100 };
	int[] yPoints1 = {190, 100, 100,  190,  290, 380, 380, 290 };
	int numPoints1 = 8;
	gr.drawPolygon(xPoints1, yPoints1, xPoints1.length);
	gr.setColor(Color.white);
	gr.fillPolygon(xPoints1, yPoints1, numPoints1);
	int[] xPoints2 = {120, 200, 280, 360, 360, 280, 200, 120 };
	int[] yPoints2 = {200, 120, 120,  200,  280, 360, 360, 280 };
	int numPoints2 = 8;
	gr.drawPolygon(xPoints2, yPoints2, xPoints2.length);
	gr.setColor(Color.red);
	gr.fillPolygon(xPoints2, yPoints2, numPoints2);
	gr.drawString(Stop, 0, 0);
	gr.setFont(new Font("Arial", Font.BOLD, 22)); 
	gr.setColor(Color.blue);
}
public static void main(String[] args){
	StopSign frame = new StopSign();
	frame.setSize(500,500);
	frame.setVisible(true);
}
}

Alright, I put the code all under the paint method. However, the text is still not visible.

[curmudgeon]

You're drawing the String at 0, 0. Test out different x and y values of where you're drawing your String to see what happens.

--- Update ---

Once you have this licked, you'll likely want to draw in the paintComponent(...) method of a JPanel that is displayed in the JFrame rather than directly in the paint(...) method of a JFrame, but one step at a time. Please have a look at the drawing with Swing tutorial: Lesson: Performing Custom Painting

Thank you I finished my code with an awesome stop sign! end result :

import javax.swing.*;
import java.awt.*;
public class StopSign extends JFrame {
String Stop = new String("STOP");
public void paint(Graphics gr){
super.paint(gr);
int[] xPoints = {90, 180, 300, 390, 390, 300, 180, 90 };
int[] yPoints = {180, 90, 90, 180, 300, 390, 390, 300 };
int numPoints = 8;
gr.drawPolygon(xPoints, yPoints, xPoints.length);
gr.setColor(Color.RED);
gr.fillPolygon(xPoints, yPoints, numPoints);
int[] xPoints1 = {100, 190, 290, 380, 380, 290, 190, 100 };
int[] yPoints1 = {190, 100, 100, 190, 290, 380, 380, 290 };
int numPoints1 = 8;
gr.drawPolygon(xPoints1, yPoints1, xPoints1.length);
gr.setColor(Color.white);
gr.fillPolygon(xPoints1, yPoints1, numPoints1);
int[] xPoints2 = {120, 200, 280, 360, 360, 280, 200, 120 };
int[] yPoints2 = {200, 120, 120, 200, 280, 360, 360, 280 };
int numPoints2 = 8;
gr.drawPolygon(xPoints2, yPoints2, xPoints2.length);
gr.setColor(Color.red);
gr.fillPolygon(xPoints2, yPoints2, numPoints2);
gr.setColor(Color.white);
gr.setFont(new Font("Arial", Font.BOLD, 85)); 
gr.drawString(Stop, 125, 260);
 
 
}
public static void main(String[] args){
StopSign frame = new StopSign();
frame.setSize(500,500);
frame.setVisible(true);
}
