Answer 1

If you want to access data directly without create any object, You can change datatype with String to long.class

`String reward = ds.child("reward").getValue(String.class);` 
      to
`long reward = ds.child("reward").getValue(long.class);`

or

public String reward;
    to
public long reward;
