Reading contacts from Mobile using JSR 75

The below Midlet explains how to read the contact names and numbers from the Phonebook using JSR 75

PIMMidelt.java
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class PIMMidelt extends MIDlet
{
ReadPIM readPim;
Display display;

public void startApp()
{
 display = Display.getDisplay(this);
 readPim  = new ReadPIM(this);
 display.setCurrent(readPim);
}
public void pauseApp()
{
}
public void destroyApp(boolean uc)
{
}
}
