    Object key = entry.getKey();
    Object val = entry.getValue();
}
Method II:

Map map = new HashMap();
for (Iterator iter = map.keySet().iterator(); iter.hasNext();) {
    Object key = iter.next();
    Object val = map.get(key);
}

Add self-define template into eclipse

Templates are little pieces of code with defined placeholders. Each template has a name, which serves as a shortcut to the template itself. You type the name and press Alt + / and it will be expanded.
like sysout:
System.out.println(${word_selection}${});${cursor}
To define your own template go to windows>Preferences>Java>Editor>Templates.



Change the content assistant key to ALT+/:
1. Go to Preferences>>General>>Keys or by typing keys in the filter box.
2. find Content Assist, change the binding to Alt+/.
3. Get rid of the association of these two keys with "word completion".
