Thanks a lot Santosh, Naresh & Richard for your invaluble input.
"Strings are constant; their values cannot be changed after they are
created. String buffers support mutable strings." & "A string buffer is
like a String, but can be modified."
Whenever I read the above Java lanuage documentation, I am a lot more
confused.
If a string is constant, I should not be able to change its value after it's
created. But I can change the value of the string at my will (My experiments
show it *). Then, why we should we use StringBuffer instead of string when
both give the same result?
Thanks and regards
BRN.

public class Strpad
{
public static void main(String[] Arg)
{
String s = "String";
String a = s;
String b = "Buffer";
String m = "mutable";
String p = "padding -> ";
String c = s+ " " + p;
for (int i = 1;i<11;i++)
c = c + i;
System.out.println(c);
System.out.println();
StringBuffer sb = new StringBuffer(s+b+" "+p);
for(int i=1;i<11;i++)
sb.append(i);
String d = sb.toString();
System.out.println(d);
System.out.println();
a = a + " is (not) " + m + "?";
System.out.println(a);
}
}
