string Buffer Doubt...

[Bhalotia Kunal]

class passstringbuf
{
 
static void stringbufmod(StringBuffer s)
{
s=null;
}
 
public static void main(String args[])
{
StringBuffer s=new StringBuffer("raja");
stringbufmod(s);
System.out.println(s);
}
 
}
 

Hi
I think the Output should be "raja". But Raja says that Output is Null. Can anybody explain if it is null.. what is the reason behind that...

The o/p will definitely be raja.
