java - String to Char Array and Char array to String Conversion -

-

In my program, I'm getting a string from the database result set and change it to four arrays like this: 

  emp.nid = rs.getString ("nid"). ToCharArray ();   
 There is no error in this section. The string has been successfully converted to four arrays, but I have another such code:  
  nid_txt.setText (Emp.nid.toString ());   
 This prints some weird text Why is this not original? Please help me   
 
 
 You are calling  toString  on  four []  - and he handles implementation with  object , so you  char [] Get the class  name, @ and then the hash of the object, instead, call  string (four [])  constructor:  
  nid_txt.setText ( New string (emp.nid));
