Output:
Reading using Reader
'H' : 72
Reading using Reader
'I' : 73
times =2
Reading using Stream
'H' : 72
Reading using Stream
'I' : 73
times =2
The file had the characters "HI". If Reader reads a character why does it have to casted into a char just like Stream , when printing using the System.out.println()?
