I would suggest putting your words into a database for the following reasons
DB lookups on android with SQLite are "fast enough" (~1ms) for even
the most impatient of usersReading large files into memory is a dangerous practice in memory-limited environments such as android.
Trying to read entries out of a file "in place" rather than "in
memory" is effectively trying to solve all the problems that SQLite
already solves for you.
Embed a database in the .apk of a distributed application [Android]
You can find more detailed examples by searching object serialization
[EDIT 1]
Map map = new HashMap();
map.put("1",new Integer(1));
map.put("2",new Integer(2));
map.put("3",new Integer(3));
FileOutputStream fos = new FileOutputStream("map.ser");
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(map);
oos.close();
FileInputStream fis = new FileInputStream("map.ser");
ObjectInputStream ois = new ObjectInputStream(fis);
Map anotherMap = (Map) ois.readObject();
ois.close();
System.out.println(anotherMap);
[EDIT 2]
try {
File file = new File(getFilesDir() + "/map.ser");
Map map = new HashMap();
map.put("1", new Integer(1));
map.put("2", new Integer(2));
map.put("3", new Integer(3));
Map anotherMap = null;
if (!file.exists()) {
FileOutputStream fos = new FileOutputStream(file);
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(map);
oos.close();
System.out.println("added");
} else {
FileInputStream fis = new FileInputStream(file);
ObjectInputStream ois = new ObjectInputStream(fis);
anotherMap = (Map) ois.readObject();
ois.close();
System.out.println(anotherMap);
}
} catch (Exception e) {
}
[EDIT 3]
Iterator myVeryOwnIterator = meMap.keySet().iterator();
while(myVeryOwnIterator.hasNext()) {
String key=(String)myVeryOwnIterator.next();
String value=(String)meMap.get(key);
// check for value
}
