Previously felt that declaring a class, and then the other package in the declaration of the value of the first class to print it out (join the introduction of the package Class) results found to be wrong look at the demo to get the correct results Importtest was run into the following import class

 package Com.ykmimi.wendu;   // There is a main to run this class import com.ykmimi.import.*;  // introduce the following package class  Public class importtest {    publicstaticvoid  main (string[] args) {       //  TODO Auto-generated method stub      new  Import ();      Ia.num (889);      Ia.printimport ();   } }

Import class

 Package com.ykmimi.Import; // by the introduction of the above  Public class Import {   int  A;     Public void num (int  num) {      this. A = num;   }      Public void Printimport () {         System.out.println (a);   }}
