Thread: Traverse through the one String and find it contains the other String

HI,
I have to write a piece of code in which i have String that can contain a word from a dictionary, that String is named 'prefix' and the dictionary word is current_word,How can i traverse through th 'prefix' to find the current_word in it

public static String getDictPhoneWord (String prefix) {

System.out.println(" :: Inside getDictPhoneWord :: prefix = "+prefix);
String current_word = "";
String phWordsFromDict = "";
// loop through the size of dictionary
for (int n = 0; n < getDictinList.size(); n++) {

// current word of dictionary
current_word = getDictinList.get(n);



if(prefix.contains(current_word))
phWordsFromDict = prefix;


}
return (phWordsFromDict);
}

it returns phWordsFromDict = "" i.e. an empty String

Please help me out

This is my code,Dictionary is a txt document that contain:
an
blau
Bo"
Boot
bo"s
da
Fee
fern
Fest
fort
je
jemand
mir
Mix
Mixer
Name
neu
o"d
Ort
so
Tor
Torf
Wasser

if one enters a phone number it should give the corresponding words from dictionary
