javascript - 读取源文件/读取文件并写入新文件后尝试删除它

Question

我正在尝试删除用于读取的源文件。但删除部分不起作用。我使用了代码，但是当我编译它时跳到其他部分

public class delete{
      public static void main (String[] args){
          BufferedReader br=null;
          BufferedWriter bw= null;

         String outFileName= "C:\\Users\\dokania\\Desktop\\New folder\\out.txt";
         File file1 = new File("C:\\Users\\dokania\\Desktop\\New folder\\casp10.txt");

          try{
              String s;
              int fileCounter=0;
              FileWriter fw = new FileWriter(outFileName);  
                          bw = new BufferedWriter(fw);

                  br=new BufferedReader(new FileReader(file1));

                    while ((s=br.readLine())!= null){
                      bw.write(s +"\n");                      
                  }
                  boolean success = (new File (file1.getName())).delete();
        if (success)
                  {
                      System.out.println(file1.getName()+ "file isdeleted");
                  }
                else
                {
                    System.out.println(file1.getName()+ "file not deleted");
                }
          }catch(IOException e) {
             e.printStackTrace();
           }
         finally{
             try{
                 if(br!=null){
                     br.close();
                   bw.close();
                 }
             }catch(IOException e) {
                e.printStackTrace();
              } 
         }

      }
}

 public static void main(String[] args) {

    BufferedReader br = null;
    BufferedWriter bw = null;

    String outFileName = "C:\\Users\\dokania\\Desktop\\New folder\\out.txt";
    File file1 = new File("C:\Users\dokania\Desktop\New folder\casp10.txt");

    try {

        String s;

        int fileCounter = 0;

        FileWriter fw = new FileWriter(outFileName);
        bw = new BufferedWriter(fw);

        br = new BufferedReader(new FileReader(file1));

        while ((s = br.readLine()) != null) {

            bw.write(s + "\n");

        }
        br.close();

        if (file1.delete()) {
            System.out.println(file1.getName() + " is deleted!");
        } else {
            System.out.println("Delete operation is failed.");
        }

    } catch (IOException e) {

        e.printStackTrace();
    } finally {

        try {

            if (br != null) {
                br.close();
                bw.close();
            }
        } catch (IOException e) {

            e.printStackTrace();
        }
    }

}
