java - Setting database records into jtextfield -

the problem of code can't set data database onto jtextfield. every time run code, says stackoverflowerror. how fix error?

here's code

public class dataconnect extends databasegui {     private connection datacon;     private statement datastmt;     private resultset datars;     private string name, address;     int age;       public dataconnect(){         try{             class.forname("com.mysql.jdbc.driver");             datacon = drivermanager.getconnection("jdbc:mysql://localhost:3306/studentrec","root","");             datastmt = datacon.createstatement();             datars = datastmt.executequery("select * studentrecords");         }catch(exception exc){             system.out.println(exc.getmessage());         }     }      public void setdata(){         try{             datars.next();             name = datars.getstring("name");             age = datars.getint("age");             address = datars.getstring("address");             databasegui dbgui = new databasegui ();              dbgui.jtfdata[0].settext(name);             dbgui.jtfdata[1].settext(integer.tostring(age));             dbgui.jtfdata[2].settext(address);            //system.out.println(name+" "+age+" "+address);          }catch(exception exc){          }      }  } 

a possible cause of problem here:

public class dataconnect extends databasegui {     //...       public dataconnect(){         //...     }      public void setdata(){         try{              databasegui dbgui = new databasegui ();  //***** 

you're creating new databasegui object within class extends databasegui , risk infinite recursion. solution: don't want dataconnect extend databasegui, or don't want create new databasegui inside of dataconnect, or both. if have displayed databasegui, don't want create non-displayed one, instead want set data of components of gui displayed, not new 1 create on spot.

also, have wonder -- create dataconnect object within databasegui class? question can improved doing bit of debugging find out code in particular causes exception occur.

also empty catch block

catch(exception exc){  } 

is code should never happen. @ least print stacktrace.
