ValueOf()

[thomas davis]

System.out.println("54321".valueOf(12345)) ;
Result : 12345
Why does it give result as given above ?

[Wirianto Djunaidi]

because valueOf() is a static method. so your call is no different than

String.valueOf(12345)

your "54321" just help establish that the method to be called belong to
the String class as opposed to Integer.valueOf(), Byte.valueOf(), etc.

"54321" is an instance of String. valueOf() is a static method of String. It's perfectly legit to access a static method via an instance, and in this case the contents of the instance make no difference. String.valueOf(12345) and "".valueOf(12345) will also produce the string 12345.
