Closeable 关闭流的简单工具

public class CloseableUtils {    private CloseableUtils(){};    //关闭对象    public static void closeQuietly(Closeable closeable){        if(closeable!=null){            try {                closeable.close();            } catch (IOException e) {                e.printStackTrace();            }        }    }}

InputStream、OutputStream、Reader、Writer类都实现了Closeable接口。
