close
public void close() -
finalize
Description copied from class:ObjectInvoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.Note that objects that override
finalizeare significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicitclosemethod (and implementCloseable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like aBigIntegerwhere typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.If you must use finalizers, consider at least providing your own
ReferenceQueueand having your own thread process that queue.Unlike constructors, finalizers are not automatically chained. You are responsible for calling
super.finalize()yourself.Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.

clone
Description copied from class:ObjectCreates and returns a copy of thisObject. The default implementation returns a so-called "shallow" copy: It creates a new instance of the same class and then copies the field values (including object references) from this instance to the new instance. A "deep" copy, in contrast, would also recursively clone nested objects. A subclass that needs to implement this kind of cloning should callsuper.clone()to create the new instance and then create deep copies of the nested, mutable objects. -
equals
Note: this doesn't check that the underlying native DecimalFormat objects' configured native DecimalFormatSymbols objects are equal. It is assumed that the caller (DecimalFormat) will check the DecimalFormatSymbols objects instead, for performance. This is also unreasonably expensive, calling down to JNI multiple times. TODO: remove this and just have DecimalFormat.equals do the right thing itself.- Overrides:
equalsin classObject- Parameters:
object- the object to compare this instance with.- Returns:
trueif the specified object is equal to thisObject;falseotherwise.- See Also:
