也许有点尴尬,但几个小时后我仍然无法用 Java 创建文件...
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;
}
我在这里错过了什么?
最佳答案
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;
}
