java复制文件范例代码

	String url1 = "F:\\SuperMap-Projects\\region.udb";// 源文件路径

        try {
        	for(int i=1;i<101;i++){
        		 String url2 = "F:\\SuperMap-Projects\\region"+i+".udb";// 目标路径（复制到E盘，重命名为b.txt）
        		 copy(url1, url2);
        	}

		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	private static void copy(String url1, String url2) throws Exception {
		FileInputStream in = new FileInputStream(new File(url1));
		FileOutputStream out = new FileOutputStream(new File(url2));
		byte[] buff = new byte[512];
		int n = 0;
		System.out.println("复制文件：" + "\n" + "源路径：" + url1 + "\n" + "目标路径："
