java - Unable to change JLabel value -


i'm new netbeans. unable run in eclipse. when try run error non static variable cannot referenced static context. please me solve.

image

inetaddress ip;  try {     ip = inetaddress.getlocalhost();     string t1= ip.gethostname();      sysname.settext(t1);               // here error     //sysname.settext("hi");           // make error } catch (unknownhostexception ex) {      logger.getlogger(mainframe.class.getname()).log(level.severe, null, ex);  }

from exception you've posted, seems code you've shown in static method, maybe main(), while variable sysname instance variable, possibly declared as

private jlabel sysname;

you cannot access instance field without instance, ie static context.
