package java.io;import java.io.IOException;/** * A {@code 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). * * @since 1.5 */public interface Closeable extends AutoCloseable {    /**     * Closes this stream and releases any system resources associated     * with it.

It is strongly advised     * to relinquish the underlying resources and to internally     * <em>mark</em> the {@code Closeable} as closed, prior to throwing     * the {@code IOException}.     *     * @throws IOException if an I/O error occurs     */    public void close() throws IOException;}

根據官方的注釋，大概翻譯是：Closeable 是可以關閉的資料來源或目標。調用 close 方法可釋放對象儲存的資源（如開啟檔案）。

關閉此流並釋放與此流關聯的所有系統資源。如果已經關閉該流，則調用此方法無效.
