this question has answer here:

image description

here model. want display users except "peter". here code: 

  //iterating through values in database             (datasnapshot postsnapshot : snapshot.getchildren()) {                 user user= postsnapshot.getvalue(user.class);                 if (user.getusername()!="peter"){                 users.add(user);}             }             //creating adapter             adapter = new myadapter(getapplicationcontext(), users);              //adding adapter recyclerview             recyclerview.setadapter(adapter);

problem: list still displays user peter!!

please use equals method compare 2 strings:

replace: if (user.getusername() != "peter")

with: if (!"peter".equals(user.getusername()))

method equals( ) compares characters inside string object. operator == compares 2 object references.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
