How to make method like getParameter()

[Huzefa Zohaib]

See the following code
public ClassA {
public static void main(String[]args) {
ClassB a= new ClassB ();
a.inter (2,'c',4);
}
}
public ClassB {
public _________ inter (int a, char c, int b) {
int d= a*b;
int e= a;
int f= b;
char g= c;
return;
}
}
what should be the reutrn type of inter(), so that I can get the value of d,e,f,g particularly when I want or when desired.
I want some thing like getParameter() which is in the HttpServletRequest object in the servlet.

When you're dealing with J2EE you'll see the 'pattern' DTO (Data Transfer Object). A DTO for your example would look something like this:

public class DEFG {
   private d, e, f, g;
   public DEFG(int d, int e, int f, int g) {
      this.d= d;
      this.e= e;
      this.f= f;
      this.g= g;
   }
   public int getD() { return d; }
   public int getE() { return e; }
   public int getF() { return f; }
   public int getG() { return g; }
}

Your 'inter' method could be rewritten as follows:

public DEFG inter(int a, char c, int b) {
   return new DEFG(a*b, a, b, c);
}

and the calling code could look something like this:

ClassB a= new ClassB();
DEFG  result= a.inter(2, 'c', 4);
int   d= result.getD();
int   e= result.getE();
int   f= result.getF();
int   g= result.getG();

kind regards
