我正在將一個文件下載到我的電腦中，然后將其移動到“C:/Program Files (x86)/MyProgram/sample.txt”問題是當我試圖將文件從下載移動到目標時這是我的代碼String website ="https://www.sample-videos.com/text/Sample-text-file-100kb.txt";       try (InputStream in = URI.create(website).toURL().openStream()) {         long x=Files.copy(in, Paths.get("C:/Users/Big Foot/Downloads/sample1.txt"));         System.out.println(x);          in.close();         File dest = new File("C:/Program Files (x86)/myProgram/sample.txt");         File source = new File("C:/Users/Big Foot/Downloads/sample1.txt");         try {             FileUtils.moveFile(source, dest);         } catch (IOException e) {             e.printStackTrace();         }       }對于重復聲明者， 我嘗試了此解決方案Solution-1 Solution-2 Solution-3但沒有解決問題這個例外在我看來java.io.FileNotFoundException: C:\Program Files (x86)\Excell To Access Convertor\sample.txt (Access is denied)at java.io.FileOutputStream.open0(Native Method)at java.io.FileOutputStream.open(Unknown Source)at java.io.FileOutputStream.<init>(Unknown Source)at java.io.FileOutputStream.<init>(Unknown Source)at org.apache.commons.io.FileUtils.doCopyFile(FileUtils.java:1123)at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:1076)at org.apache.commons.io.FileUtils.copyFile(FileUtils.java:1028)at org.apache.commons.io.FileUtils.moveFile(FileUtils.java:3008)at download.main(download.java:31)
