Closeable

  • The Closeable interface represents data sources or destinations that can be closed to release resources like open files.

  • It extends the AutoCloseable interface and requires implementing the close() method.

  • The close() method is crucial for resource management, ensuring system resources are freed when no longer needed.

  • Implementations should handle potential IOExceptions during closing, prioritizing resource release and marking the object as closed.

public interface Closeable implements AutoCloseable
Known Indirect Subclasses

A Closeable is a source or destination of data that can be closed. The close method is invoked to release resources that the object is holding (such as open files).

Public Method Summary

abstract void
close()
Closes this stream and releases any system resources associated with it.

Inherited Method Summary

Public Methods

public abstract void close ()

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable.close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.

Throws
IOException if an I/O error occurs
