Recursively read all files under the file path:

Output content to (append) TXT file to save:

 
 测试：
 
进行测试，读取“E:\图书\图书馆\小说杂文”下的所有文件，并将结果输出到 “C:\Users\Administrator\Desktop\fileNameList.txt”中。测试代码如下：
 
 fileNameList = readFiles1(filePath,new ArrayList
    
    
  ());
            Sy
  stem.out.println(fileNameList.size());
            for (int i = 0; i < fileNameList.size(); i++) {
                outputToTxt(fileNameList.get(i),outputPath1);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

 
   
   
测试结果如下：
这是文件路径，路径下面有一个新建文件夹和若干个txt文件，共1086个对象，新建文件夹下面共有10个txt文件，计算可得此路径下面共有1086+10-1=1095个txt个文件：
