String to Char Array and Char array to String Conversion

Question

In my program I am getting a string from Database result set and convert it to char array like this:

emp.nid = rs.getString("nid").toCharArray();

In this part there is no error. The String is successfully converted to char array. But I have another code like this:

nid_txt.setText(emp.nid.toString());

This prints some freaky text. Not the original. Why was this happens? Please help me.

Answer 1

You're calling toString on a char[] - and that inherits the implementation from Object, so you get the char[].class name, @ and then the hash of the object. Instead, call the String(char[]) constructor:

nid_txt.setText(new String(emp.nid));
