Doubt related two string

[hirak1984]

Can there be any condition between two strings( say "a" and "b" ) where
a.equals(b) returns true
but
b.equals(a) returns false ?

that's a set of strings. nice to do that in java

No, it is a symetric relation: if a equals b, b equals a.

thanks for your correction prometheuz. answer is no. String comparison follows character mappings. I saw containment when i threw that answer

[hirak1984]

well thanks for the answer.. to both of you

I wish that Gosling and his mates had thought a bit more and put in a less()
method in the Object class too instead of just an equals() method. The default
implementation could have been:

[code=java]
bublic boolean less(Object that) return this.hashCode() < that.hashCode() ; }
[/code]

We wouldn't have needed that silly Comparable interface then.

kind regards,
