为什么Java在catch块内返回statment不起作用？

public boolean write (ArrayList<String> inputText,String locationToSave){

    try {           
        File fileDir = new File(locationToSave);
        Writer out = new BufferedWriter(new OutputStreamWriter(
        new FileOutputStream(fileDir),"utf8"));

        int index = 0;
        int size = inputText.size();
        while (index < size) {
                    out.append(inputText.get(index));
                    out.append("n");
                    index++;
                    }
        out.flush();
        out.close();

        return true;

   } catch (UnsupportedEncodingException e) {
        System.out.println("UnsupportedEncodingException is : n" + e.getMessage());
        return false;
   } catch (IOException e) {
        System.out.println("IOException is : n" + e.getMessage());
        return false;
   } catch (Exception e) {
        System.out.println("Exception is : n" + e.getMessage());
        return false;
   }
}

这是我用来测试前面代码的代码：

if (fileReader.write(fileReader.read(selectedFile),selectedSaveLocation)) {
        System.out.println("The file : " + selectedFile + " as been successfully"
        + "converted to : " + selectedSaveLocation );
    } else {
        System.out.println("The file : " + selectedFile + " failed to convert!" );
    }
