 Int to char      –        Char b=(char)a;

 int to long      --        long b=Long.valueOf(a);

int to double   --        double b=a;

int to float       --        float b=a;

                                         String

String a="harsh";

int index=1

String to char -- char b=a.charAt(index);

String to int --       int b=Integer.parseInt("10");

String to long --   long b=Integer.parseInt("10");

String to double--   double b=Float.parseFloat("10.00");

String to float--   float b=Float.parseFloat("10.00");
