如何在java（而不是文件夹）中创建文件？
问题描述：
也许有点尴尬，但几个小时后我仍然无法用Java创建文件...
Perhaps somewhat embarassing, but after some hours I still cannot create a file in Java...
File file = new File(dirName + "/" + fileName);
try
{
// --> ** this statement gives an exception 'the system cannot find the path'
file.createNewFile();
// --> ** this creates a folder also named a directory with the name fileName
file.mkdirs();
System.out.println("file != null");
return file;
}
catch (Exception e)
{
System.out.println(e.getMessage());
return null;
}
我在这里缺少什么？
答
首先尝试创建父目录：
File file = new File(dirName + File.separator + fileName);
try {
file.getParentFile().mkdirs();
file.createNewFile();
System.out.println("file != null");
return file;
}
catch (Exception e)
{
System.out.println(e.getMessage());
return null;
}
