Storing string value in java

You can split the string :

String myString = "1_2_5_7_12_"; String numbers[] = myString.split("_"); int num[] = new int[numbers.length]; int i=0; for(String s : numbers){ num[i] = Integer.parseInt(s); i++; } 

So now the array num will contain integers in that string.

try as using Pattern.compile for split String to Array:

 String str = "1_2_5_7_12_"; String[] strarray=Pattern.compile("-").split(str); 

and for storing or retrieve value from SharedPreferences see

http://developer.android.com/guide/topics/data/data-storage.html#pref

to save

SharedPreference.edit().putString(value, default).commit() 

to get value

SharedPreference.getString(value, default) 

to split the string

String.split("_") to split 

Eventually it's gonna be a string, so i do not see any problem to store it in Sharedpreference . And you can split it as in @Shreya Shah's response

you can do by this..

 final SharedPreferences pref1 = getSharedPreferences("My_App", MODE_PRIVATE); SharedPreferences.Editor editor = pref1.edit(); editor.putString("str", "yourString"); editor.commit(); 

Save like this:

SharedPreferences prefs = getApplicationContext().getSharedPreferences("prefs", Context.MODE_PRIVATE); Editor prefsEditor = prefs .edit(); prefsEditor.putString("myString", "1_2_5_7_12"); prefsEditor.commit(); 

and retrieve like this:

String str= prefs.getString("myString", ""); 

after that you can split your string simply by doing

String[] strArr = str.split("_"); 

For saving string you can use SharedPreferences or string.xml file. For splitting the string

String text = "1_2_5_7_12_"; String[] splits = text.split("_"); 

use this code ....

public static ArrayList<String> strDRIVERS = new ArrayList<String>(); String DNAME="1_2_5_7_12"; if(DNAMES.length()>0){ String[] arr_drivers = DNAMES.split(","); for(String sx : arr_drivers){ strDRIVERS.add(sx); } }
