toString
public java.lang.String toString()
- Description copied from class:
java.lang.Object
- Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into System.out.println() 55
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a java.lang.RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use "null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
equals
public boolean equals(java.lang.Object other)
- Description copied from class:
java.lang.Object
- Determine whether this Object is semantically equal
to another Object.
There are some fairly strict requirements on this
method which subclasses must follow:
- It must be transitive. If
a.equals(b) and
b.equals(c), then a.equals(c)
must be true as well.
- It must be symmetric.
a.equals(b) and
b.equals(a) must have the same value.
- It must be reflexive.
a.equals(a) must
always be true.
- It must be consistent. Whichever value a.equals(b)
returns on the first invocation must be the value
returned on all later invocations.
a.equals(null) must be false.- It must be consistent with hashCode(). That is,
a.equals(b) must imply
a.hashCode() == b.hashCode().
The reverse is not true; two objects that are not
equal may have the same hashcode, but that has
the potential to harm hashing performance.
This is typically overridden to throw a java.lang.ClassCastException
if the argument is not comparable to the class performing
the comparison, but that is not a requirement. It is legal
for a.equals(b) to be true even though
a.getClass() != b.getClass(). Also, it
is typical to never cause a java.lang.NullPointerException.
In general, the Collections API (java.util) use the
equals method rather than the ==
operator to compare objects. However, java.util.IdentityHashMap
is an exception to this rule, for its own good reasons.
The default implementation returns this == o.
