Trouble with threads and awt

Question

Hello everyone I have some code that I'll like to thread, I'll like to draw two lines that prints alternatively one after the other in a blinking effect usig thrreads but the code is not functioning the way I'll like it too, please can someone take a look at it for me?
import java.applet.*;
import java.awt.*;
public class ArgueRunnable extends Applet implements Runnable{
  Thread myThread;
    int width, height;
boolean running= true;
   public void init() {
      width = getSize().width;
      height = getSize().height;
      setBackground(Color.white);
      myThread = new Thread(this);
      myThread.start();
  public void run() {
    try {
      for(;;) {
        repaint();
        myThread.sleep(33);
        repaint();
    catch (InterruptedException e) {
      return;
public void paint(Graphics g){
  update1(g);
  update2(g);
public void update1( Graphics g ) {
       g.drawLine(0, 15, 200, 15);
public void update2( Graphics g ) {
       g.drawLine(100, 15, 200, 15);
   

Answer 1

Hello again, thanks for sending the code, however there were a couple syntax errors, which was easy to fix, but the code still did not work the way I expected I'm still not getting the blinking effect I'm trying to accomplish, can you look at it again for me?{import java.applet.*;
import java.awt.*;
public class ArgueRunnable2 extends Applet implements Runnable{
       Thread myThread;
         int width, height;
     boolean running= true;
     boolean up1 = true;
     int x=200;
     int y=200;
   public void init() {
      width = getSize().width;
      height = getSize().height;
      setBackground(Color.white);
      myThread = new Thread(this);
      myThread.start();
  public void run() {
        while (true)
          try {
               myThread.sleep(500);
          catch(Exception e){
          if (up1==true){
               up1=false;
               if(up1==false){
               up1=true;
          repaint();
     public void paint(Graphics g){
          if (up1 == true){
                 update1(g);
               x=0;
               y=200;
          else{
               update2(g);
               x=200;
               y=0;
public void update1( Graphics g ) {
     g.setColor(Color.red);
       g.drawLine(0, 15,y, 15);
public void update2( Graphics g ) {
     g.setColor(Color.blue);
       g.drawLine(100, 15, x, 15);
