Java: Assigning Non Static Variable to Static Variable -

i'm using class called globalvar store global variables required entire application. class looks this:

public class globalvar {      myprops props = new myprops();      public globalvar() throws exception     {      }      public static string ppfirstname = "kim";     public static string pplastname = "smith";       string zip = props.props.getipzip("ipzip");     public static string ipzip = zip;  } 

however, in last 2 lines i'm getting error:

cannot assign non static variable static variable.  

i understand source of problem (as zip non static , ipzip static) question is: there way around this? i.e, way assign value set in "props" "ipzip" static var?

note: purpose of using method able use syntax globalvar.ipzip anywhere in application..

you creating instance of myprops, calling non-static getipzip method. cannot assign result of non-static method static variable.

instead, need convert getipzip method static method of myprops class, assign result yor ipzip variable this.

public static string ipzip = myprops.getipzip("ipzip"); 

then access ipzip anywhere using globalvar.ipzip.

however, if make getipzip method static, adding variable globalvar class unnecessary, call myprops.getipzip("ipzip"); anywhere in code.

another option move getipzip method globalvar class , make static method in there, call globalvar.getipzip("ipzip");.
