int/char???

<font size="+0">
class InheritanceTest extends Process { 
  int x=18; 
  
  public static void main(String [] args) { 
    Process p = new InheritanceTest(); 
    System.out.println(p.InheritanceTest('R')); 
    System.out.println(p.x); 
  } 
  
  InheritanceTest() { 
    System.out.println(true ^ true);

  InheritanceTest(char c) { 
    System.out.println(c); 
  } 
  
  char InheritanceTest(char c) { 
    c='V'; 
    return (char)c; 
  } 
  } 
  
  class Process { 
   int x=9; 
  
   Process() { 
     System.out.println("Starting Process..."); 
   } 
  
   char InheritanceTest(int i) { 
     i='S'; 
     return (char)i; 
   } 
 } 

----------------------------
The o/p is:-
Starting Process...
false
S
9
----------------------------
shouldn't it be 'R'instead of 'S'. though the one with int arg is inherited in the subclass the one with char arg is more specific, isn't it?? can somebody help me out!!!

There is no method named InheritanceTest() taking char as argument in the class Process. So there is no dynamic lookup(needs method to be defined in both subclass & Baseclass). And the invocation of the method taking int in class Process takes place printing 'S' instead of 'R' as you expected.
