Try catch finally – Java – Fórum – Programujte.com

Čau.

Uprostřed programu potřebuji zkopírovat soubor a zamotal jsem se do konstruktoru try-catch-finally.

Respektive mi to u bloku finally píše: unreported exception IOException, must be caught or declared to be thrown.

Jak to mám upravit aby to šlapalo? Díkes

            InputStream in = null;
            OutputStream out = null;
            try {
                in = new FileInputStream("C:\\fileA.mdb");
                out = new FileOutputStream("C:\\fileB.mdb");

                byte[] buffer = new byte[1024];
                int numRead;

                while ((numRead = in.read(buffer)) != -1) {
                    out.write(buffer, 0, numRead);
                }

            } catch (IOException e) {
            } finally {
                in.close();
                out.close();
            }

do finally daj dalsi try ... samotny in/out nemusi existovat a teda by ti to hadzalo exception pri jeho zatvarani

finally {
			try {
				if (in != null)
					in.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
			try {
				if (out != null)
					out.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}

Díky!:)
