First make a pojo class of User data . 

Class User {
 String about;
 String email;
 String image;
 String name;
 String password;
 String pointsTotal;
 String totalTasksDone;
}

Make getter setters and define constructors.

mUserCompounds.orderByChild("email").equalTo("[email protected]").addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    if (dataSnapshot.exists()) {
                         //User already exists
                         User user1 = dataSnapshot.getValue(User.class); 
                         System.out.println(user1.getPassword());
                       }
                  }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });

this is pretty simple

mUserCompounds.orderByChild("email").equalTo("[email protected]").addValueEventListener(new ValueEventListener() {
                        @Override
                        public void onDataChange(DataSnapshot dataSnapshot) {

                        Log.i("your tag",""+dataSnapshot.toString());
    }

                        @Override
                        public void onCancelled(DatabaseError databaseError) {

                        }
                    });
