    In Java, is a string an object?

    OK, it passes the value of the reference, not the value of the object into a method. When the new reference (in the mothod) pointes to another string object the original reference remains pointing to the original object.

    In Java, is a string an object?

    sedj, Thank you for your response. If a String is unchangeable, there must a copy of the string, not the copy of its reference, in the above method (so that it can be changed in the method while not affect the string in the main). That means an object (the string) is copied in the method!
