Programming logic

Question

I want help in one programming logic.For that I make small example ,so that can explain clearly.
public class Mainclass //(situated in package view)
public s0,s1;
public void runFunction()
...some coding and proceedings
s0="Hi";s1"Hello";
......some coding
public MainRunner
public static void main(String a[])
Mainclass m=new Mainclass();
m.runFunction();
public MainUser (situated in package Master)
public static void main(String a[])
Mainclass m=new Mainclass();
System.out.println("S0:"+s0+" S1:"+s1); //should print S0:Hi S1:Hello, but printing S0:null S1:null
In this ,I first run the MainRunner and then MainUser after compiling the classes and expect that print command of MainUser would give me -S0:Hi S1:Hello as result ,but it is yielding the null values for s0 & s1.
What should I do in this to get hi for s0 and hello for s1.

Answer 1

hi friend, plz follow the code. I think this code may be suitable for u r requirements...
class MainUser
     public String s0,s1;
     MainUser()//Here i am using Constructor
          s0="Hi";s1="Hello";
public class C extends MainUser
     public static void main(String a[])
          MainUser m=new MainUser();
          System.out.println("S0:"+m.s0+" S1:"+m.s1);
                    (OR)
class MainUser
     static String s0,s1;//Here i am declaring variables as Static
     public void runFunction()
          s0="Hi";s1="Hello";
class B extends MainUser
     public B()//Contructor
          MainUser m=new MainUser();
          m.runFunction();
public class C extends B
     public static void main(String a[])
          B b=new B();//when i am creating new Object b then it will call B constructor
          System.out.println("S0:"+b.s0+" S1:"+b.s1);
byeeeee
