import java.util.Iterator;

private JTextComponent comp;

public static String z;

public static String[] dict = { "Team", "meeting", "project", "review","client","call","orginization","team" };

public AutoCompleteDocument( JTextComponent field, String[] aDictionary ) {

comp = field;

dictionary.addAll( Arrays.asList( aDictionary ) );

}

public void addDictionaryEntry( String item ) {

dictionary.add( item );

}

public void insertString(int offs, String str, AttributeSet a)

throws BadLocationException {

super.insertString( offs, str, a );

String word = autoComplete( getText( 0, getLength() ) );

if( word != null ) {

super.insertString( offs + str.length(), word, a );

comp.setCaretPosition( offs + str.length() );

comp.moveCaretPosition( getLength() );

}

}

public String autoComplete( String text ) {

for( Iterator i = dictionary.iterator(); i.hasNext(); ) {

String word = (String) i.next();

if( word.startsWith( text ) ) {

return word.substring( text.length() );

}

}

return null;

}

/**

JTextField field = new JTextField();

AutoCompleteDocument doc = new AutoCompleteDocument( field,dictionary );

field.setDocument(doc);

// z = field.getText();

System.out.println("Stirng out side the key pressed "+z);

field.addKeyListener(new java.awt.event.KeyAdapter()
