Why static varible in Java program not retaining its value?

I am calculating this java programme output…Here for first print statement….I get F….and after calling krinsh(c) metod….I get char c=190….According to ascII 190 represents 3/4…..and as c was declared as static its value should change to 190 and retain its value……so for second print statement I should get 3/4…..But when I execute the program I get F for both Print statement…..I tried to print c inside krish method but then I get 3/4……why am I not getting c=3/4 in the second print statement inside main method.

  public class Krish {
     static char c = 70;
     public static void main(String[] args) {
      Krish krish = new Krish();
      System.out.print(c + " ");
      krish(c);
      System.out.println(c);
     }
     static void krish(char c) {
       int cr = c;
       cr = cr * 2;
       cr = cr + c - 20;
       c = (char) cr;
     }
    }

>Solution :

You have to set c in this way: Krish.c = (char) cr;, otherwise you’re setting the local variable in krish method instead of the static variable (Krish.c).
