Aim: –Write a program to access data from a specific URL. The stream connection is used to connect the application to specific URL by Airtime.
import java.io.*;
import javax.microedition.io.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class AccessUrl extends MIDlet
{
private Display display;
String url = “http://localhost/AccessURL/hello.txt”;
public AccessUrl()
{
display = Display.getDisplay(this);
}
public void startApp()
{
Try
{
connection(url);
}
catch (IOException e)
{
System.out.println(“IOException ” + e);
e.printStackTrace();
}
}
public void pauseApp(){}
public void destroyApp(boolean unconditional){}
void connection(String url) throws IOException
{
StreamConnection sc = null;
InputStream is = null;
StringBuffer buffer = new StringBuffer();
TextBox access;
Try
{
sc = (StreamConnection)Connector.open(url);
is = sc.openInputStream();
int chars;
while((chars = is.read()) != -1)
{
buffer.append((char) chars);
}
System.out.println(buffer.toString());
access = new TextBox(“Access Text”, buffer.toString(), 1024, 0);
}
Finally
{
if(is != null)
{
is.close();
}
if(sc != null)
{
sc.close();
}
}
display.setCurrent(access);
}
}
Output:-
