The format of the string Object.toString returns by default - which of the following is true?
Answer: C
The javadoc defines it exactly as getClass().getName() + '@' + Integer.toHexString(hashCode()), giving output such as java.lang.Object@1b6d3586. The number is a hexadecimal hash code, not an address and not a decimal, and it is the usual sign that a class has not overridden toString.
