[code]
Which methods can be legally applied to a string object?
a.equals(String)
b.equals(Object)
c.trim()
d.round()
e.toString()
the answer is a b c d e
my question is focus on a.
because i have viewd the api for jdk1.3 and i merely find the method of equals(Object obj) at the the class of String.So i think the answer shouldn't include a.
my english is poor so i don't know if i explain clearly.

A String "is an" Object and is therefore a legal argument to any method which takes an Object as a parameter.

Also, d is incorrect. You cannot round() a String.
