i am pretty new to java and am racking my brain in the process. i have been getting a few errors on my program and cant figure them out. i posted my code below. is is unfinished, so it will look a little broken, but should still compile and run. the errors i am getting are:
non-static variable firstName/lastName cannot be referenced from a static context firstName = name.substring( 0, whitespace); lastName = name.substring( whitespace = 1);
cannot resolve symbol showInfo( String name --its pointing to the beginning of String
incompatible types found : void required : java.lang.string shows up in both : String info = JOptionPane.showMessageDialog.... & return JOptionPane.showMessage Dialog.... (in java:124) i even asked my teacher about this error, and she couldnt tell me.
sorry i dont have any dukes to give out, i already gave them all away. but i would surely appreciate some help. i am racking my brain, and trying to grasp. it is coming, slowly, but surely. thanks!
