Method Detail

equals

public final boolean equals(Object o)
Description copied from class: Object
Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

This is typically overridden to throw a 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 NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.

Overrides:
equals in class Object
Parameters:
o - the Object to compare to
Returns:
whether this Object is semantically equal to another

Object.hashCode()

hashCode

public final int hashCode()
Description copied from class: Object
Get a value that represents this Object, as uniquely as possible within the confines of an int.

There are some requirements on this method which subclasses must follow:

Notice that since hashCode is used in Hashtable and other hashing classes, a poor implementation will degrade the performance of hashing (so don't blindly implement it as returning a constant!). Also, if calculating the hash is time-consuming, a class may consider caching the results.

The default implementation returns System.identityHashCode(this)

Overrides:
hashCode in class Object
Returns:
the hash code for this Object
See Also:
Object.equals(Object), System.identityHashCode(Object)

toString

public String toString()
Return the name of this Type.

Overrides:
toString in class Object
Returns:
the String representing this Object, which may be null
