removing the value from a object in java or android -

private string[] userkeys;  userkeys =  mhconstants.friendsmodeldetails.keyset().toarray( new string[mhconstants.friendsmodeldetails.size()]);  if(mhconstants.friendsmodeldetails.size()>0 ){         for(int = 0;i<mhconstants.friendsmodeldetails.size();i++){             string username = userkeys[i];  system.out.println("userkey contains"+username); } string number=9; 

this prints 1 5 9 8 10

how can position of value equal ''number'' , delete userskey... in advance.

you can try apache commons

userkeys = arrayutils.removeelement(userkeys , number);  

or iterating through array , shifting elements can same.
(its ugly , not tried/tested)

string number = "9"; boolean flag = false; int j; int length = userkeys.length; (int = 0; < length; i++) {     if(number.equals(userkeys[i])){         flag = true;         j = i;     } } if(flag){     for(int i=j;i<length-1;i++){         userkeys[i+1] = userkeys[i];     }     userkeys[length] = null; // resetting value }
